Abstract:
TiAlON/TiAlN/TiAl hard films are prepared by multi-arc ion plating technology using the Ti-50Al (at%) alloy target. The high speed steel (HSS) is adopted as substrate. The surface and cross-fracture morphology, the surface and cross-fracture compositions and the phase structures of the as-deposited TiAlON/TiAlN/TiAl hard films are observed and measured by scan electronic microscope (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). The mechanical properties, including micro-hardness and adhesive strength between film and substrate, of the as-deposited TiAlON/TiAlN/TiAl hard films are investigated. The effects of oxygen partial pressure on the as-deposited films are discussed. It is revealed that the increase of oxygen decreased liquid droplets distribution density to some extent, caused complicated phase structure. Nevertheless, the good adhesive strength and the improved hardness with a maximum of 3900HV are achieved.

Abstract:
Two series of TiAlN and Ti3AlN films have been deposited on Si (100) substrates by reactive magnetron sputtering TiAl and Ti3Al targets in Ar/N2 mixture. The effects of incoming ions energies controlled by Vb on the microstructure, morphologies, residual stress and hardness have been explored by XRD, SEM, AFM, surface profiler and nanoindentation. The results showed that single phase cubic Ti-Al-N solid solubility formed by Al atoms replacing some Ti atoms in the cubic TiN lattice occured in both TiAlN and Ti3AlN films. As substrate bias increased, the preferred orientation firstly changed from (111) to (200), and then returned to (111) at higher substrate bias. At the same time, high substrate bias promoted the densification of films and presence of high compressive stress, which is benefit for improvement of hardness.

Abstract:
TiAlN, and TiAlN/CrN nanolayered coatings were synthesized by cathodic-arc evaporation with plasma enhanced duct equipment. Chromium and TiAl (50/50 at %) alloy cathodes were used for the deposition of TiAlN/CrN coatings. The effects of bilayer thickness and chromium content on the microstructure and mechanical properties of TiAlN/CrN nanolayered coatings were studied. The preferred orientation was changed from (200) in TiAlN monolayered coatings to (111) plane in the multilayered TiAlN/CrN coatings. The multilayered TiAlN/CrN coating with periodic thickness of 20 nm and the smallest crystallite size of 28 nm exhibited the highest hardness of 39 GPa. The multilayered TiAlN/CrN coatings also showed the best adhesion strength using scratch tests. It has been found that the structural and mechanical properties of the films were correlated with the addition of chromium and nanolayer thickness.

Abstract:
The combinations of TiAl-doped DLC and TiAlN/TiN layers were designed to deposit on the tool steels using cathodic arc evaporation in a continuously single batch process. The economic advantage in depositing the combined coating in one production scale of PVD system is of practical importance. The TiAl-doped DLC as lubricant coatings were synthesized by using arc plasma sources mounted with Ti50Al50-target to emit high energy ion plasma to activate the decomposition of acetylene reactive gases. The results show that the TiAl-doped DLC and TiAlN/TiN combined coatings retained lower friction coefficient at approximately 0.15 during the steady-state sliding. The lubricity and wear resistance of TiAl-doped DLC/TiAlN/TiN coatings is then demonstrated to potentially be applied to the cutting tools with no lubricants.

Abstract:
This paper originates from a large EU programme designed to produce high performance coatings with superior mechanical and corrosion resistance properties to enhance high temperature corrosion behaviour of TiAl based alloy (Ti45Al8Nb).The paper here is concerned with studies of the hot corrosion behaviour of Ti – Aluminide alloys (Ti45Al8Nb mainly -TiAl with small amount 2 (Ti3Al)) coated with three coatings: (1) TiAlYN/CrN coating, (2) CrAl with 2%YN addition [1,2] (3) TiAlN with Al2O3 overlayer. Hot corrosion was induced by spraying salts mixture of 80%Na2SO4/20%NaCl with melting point around 700oC [1] [2] on heated sample surfaces, and subsequently heating the sprayed samples in a furnace at 750oC for various times. The extent of degradation, assessed by weight changes and examination by OM (Optical Microscope), SEM (Scanning Electron Microscope), and EDX (Energy Dispersive X-Ray Analysis) indicated that all samples suffered hot corrosion attack to various degrees. TiAlN with Al2O3 overlayer had the best corrosion resistance.We shall discuss these results within a mechanistic framework of hot corrosion degradation and describe their implications.

Abstract:
TiAl and TiAlN thin films are deposited on glassy carbon and Si substrates by the pulsed cathodic arc deposition process. In our pulsed cathodic arc system, because the spatial position of plasma on the surface of the evaporation source can be controlled by pulsed arc discharge, the thickness of the TiAl and TiAlN films can be controlled at nanometer scale. Amorphous stoichiometric Ti-Al films are synthesized from one Ti-Al alloy target at room temperature by changing the number of pulses of the arc discharge.

Abstract:
Ring is one of the major textile spinning machine consumable part, it has an important influence on yarn quality and cost. Ring of domestic cotton spinning enterprises generally has poor hardness, bad accuracy, not durable and difficult to guarantee the quality of the yarn, foreign ring has excellent performance, but it is too expensive, so it is difficult to widely used in China[1]. Vacuum arc ion plating technology has a wide range of applications in the aerospace, automobile, mold, tool, electronics and other fields [2-3]. TiN film which is prepared by arc ion plating technology has been widely used because of the TiN film has poor oxidation resistance and wear resistance at high temperatures, so the ternary films are developed on TiN film, such as TiAlN [4], TiCN etc. Traveller circle in the ring on the slide to produce large amounts of heat, it makes the ring surface temperature reach 400°C. When higher than 400°C, the TiCN film failure, therefore, ring should not be plated on the TiCN films. While TiAlN film oxidation temperature reaches 800°C. In HSS twist drill, depositing of TiAlN film can improve the service life more than four times [5]. Studies [6-8] have found that using pulsed laser deposition and chemical vapor deposition technique to prepare TiAlCN film, its wear resistance, high temperature stability is better. Pulsed laser deposition is mainly used in laboratory research. It is difficult to deposit a large area uniform film. Chemical vapor deposition of deposition rate is less than the arc ion plating, and produces lots of waste gas, leading to the environment is polluted. Arc ion plating technology can deposit the uniform films of large area with high deposition rate and deposition with no environmental pollution, therefore, this study, by means of vacuum arc ion plating technology to prepare high-precision, long-life and low-cost domestic cotton spinning ring. In order to obtain the best film process parameters, the performance of film is investigated at different bias and arc current.

Abstract:
This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 μ m) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C). Flaking wear resistance decreased with increased coating thickness for all coating types. Further the high temperature version of Coating A, showed a significant increase in the flaking wear resistance compared to the standard version of Coating A. The flank wear test showed an increased resistance with thicker coatings in all cases except for the 6 μ m version of Coating C. The flank wear resistance of the most flank wear resistant coatings (Coating B, C) was also successfully examined in a new developed test method. The method suppressed excessive crater wear on the rake face and presented a high abrasive wear rate on the flank and some flaking on the rake face. The amount of flaking is judged not to influence the testing of the flank wear resistance. For all the tested coatings in the new test an increase in the coating thickness resulted in better flank wear resistance.

Abstract:
The oxidation behaviour of TiAlN based hard coatings with the addition of Cr and/or Y was investigated using scanning electron microscopy, scanning/transmission electron microscopy, energy dispersive X-ray analysis, thermogravimetry and X-ray diffraction. The coatings were deposited using the combined cathodic arc/unbalanced magnetron deposition technique. The main practical application of these films is dry high speed cutting in difficult to cut materials such as AISI A2 steel. Especially in the case of TiAlCrYN coating with an oxynitride and Cr-enriched overcoat, extensive research on the oxidation behaviour was performed and described here. Heat treatments in air between 600-1000°C for different duration were carried out. The Ti[0.44]Al[0.54]Cr[0.02]N coating was used as the starting point for the investigations. The effect of heat on the composition of the interface region was investigated. This region is of utmost importance for the adhesion of the film. In the case of TiAICrN the interface stability was not guaranteed because of diffusion of the substrate elements Cr and Fe to the coating surface after annealing for 1h at 900°C. In comparison, the diffusion of substrate elements Cr and Fe in a ~2.3 mum thick coating of Ti[0.43]Al[0.52]Cr[0.03]Y[0.02]N and of Ti[0.34]Al[0.62]Cr[0.03]Y[0.01]N with overcoat, reached only a distance of ~600nm into the coating. This was achieved by the diffusion of Y to the grain boundaries. Y probably reacted at the same time with inward diffusing O. The diffusion of Y to the boundaries was observed after heat treatment for 1h at 900°C or 10h at 800°C.Ti[0.26]Al[0.26]N/Cr[0.48]N was the coating with the least oxide layer growth after oxidation for 1h at 900°C. An oxide layer thickness of only ~100nm was measured. For the TiAICrYN coating with overcoat an oxide layer of 230nm and for TiAICrYN of 430nm formed after 1h at 900°C. TiAlCrN in comparison formed an oxide layer of ~800nm after 1 h at 900°C.The oxide layers formed after 1h at 900°C consisted mainly of an Al[2]O[3] and TiO[2] bi-layer in the case of TiAlCrN and TiAlCrYN. The addition of a Cr-rich oxynitride overcoat led to the formation of a mixture out of Al[2]O[3], Cr[2]O[3] and TiO[2] in the oxide layer. In the case of TiAlN/CrN, a solid solution consisting of Cr[2]O[3] and Al[2]O[3] was observed. In general a stress relief after heat treatment was observed. At the same time the formation of voids along the column boundaries was identified. This was explained with the relaxation and diffusion of defects created during the deposition process. The effect of different substrate materials on the oxidation behaviour was also investigated. It was found that the formation of substrate oxides on the coating surface is very much dependent on the onset point of oxidation of the substrate material itself. The oxidation of substrate material occurred mainly through growth defects and pinholes. In cases where cracks formed during heat treatment of the coating, the formation of oxides out of substrate elements were observed in cracks connecting the substrate with the coating surface. Changing the bias voltage altered the formation of cracks. This research emphasises the importance of Y in the oxidation mechanism of TiAlN based hard coatings. Y blocks the diffusion path along the column boundaries and thus stowed down the diffusion and oxidation process. At the same time the addition of Cr can increase the oxidation resistance considerably, which was observed in the TiAlCrYN coating with and without overcoat.

Abstract:
TiAlN  thin  films  are  used  commercially  in  the  cutting  tool  industry  as  wear protection  of  the  inserts.  During  cutting,  the  inserts  are  subjected  to  high temperatures (~ 900  ° C and sometimes higher). The  objective of this work is to simulate the material behavior at such high temperatures. TiAlN has been studied experimentally at least for two decades, but no microstructure simulations have so far been performed. In this thesis two models are presented, one based on regular solution and one that takes into account clustering effects on the thermodynamic data.  Both  models  include  anisotropic  elasticity  and  lattice  parameters  deviation from  Vegard’s  law.  The  input  parameters  used  in  the  simulations  are ab  initio calculations and experimental data.Methods for extracting diffusivities and activation energies as well as Young’s modulus  from  phase  field  results  are  presented.  Specifically,  strains,  von  Mises stresses,  energies,  and  microstructure  evolution  have  been  studied  during  the spinodal  decomposition of  TiAlN. It  has  been  found  that  strains  and  stresses  are generated during the decomposition i.e. von Mises stresses ranging between 5 and 7.5  GPa  are  typically  seen.  The  stresses  give  rise  to  a  strongly  composition dependent  elastic  energy  that  together  with  the  composition  dependent  gradient energy   determine   the   decomposed   microstructure.   Hence,   the   evolving microstructure depends strongly on the global composition. Morphologies ranging from isotropic, round domains to entangled outstretched domains can be achievedby  changing  the  Al  content.  Moreover,  the  compositional  wavelength  of  the evolved  domains  during  decomposition  is  also  composition  dependent  and  it decreases with  increasing  Al  content.  Comparing  the  compositional  wavelength evolution extracted from simulations and small angle X-ray scattering experiments show that the decomposition of TiAlN occurs in two stages; first an initial stage of constant  wavelength and  then  a  second  stage  with  an  increasing  wavelength are observed.  This  finding  is  characteristic  for  spinodal  decomposition  and  offers conclusive evidence that an ordering transformation occurs. The Young’s modulus evolution  for  Ti 0.33 Al 0.67 N  shows  an  increase  of  5%  to  ~398  GPa  during  the simulated decomposition.

Abstract:
This licentiate thesis mainly reports about the behavior of arc evaporated TiAlN at high pressures and high temperatures. The extreme conditions have been obtained in metal cutting, multi anvil presses or diamond anvil cells. Several characterization techniques have been used, including x-ray diffraction and transmission electron microscopy. Results obtained during metal cutting show that the coatings are subjected to a peak normal stress in the GPa region and temperatures around 900 °C. The samples after metal cutting are shown to have a stronger tendency towards the favorable spinodal decomposition compared to heat treatments at comparable temperatures. We have also shown an increased anisotropy of the spinodally decomposed domains which scales with Al composition and results in different microstructure evolutions. Furthermore, multi anvil press and diamond anvil cell at even higher pressures and temperatures (up to 23 GPa and 2200 °C) also show that the unwanted transformation of cubic AlN into hexagonal AlN is suppressed with an increased pressure and/or temperature.

Abstract:
TiAlN and TiAlN-based coatings that are used of relevance as protection of cutting tool inserts used in metal machining have been studied. All coatings were deposited by reactive cathodic arc evaporation using industrial scale deposition systems. The metal content of the coatings was varied by using different combinations of compound cathodes. The as-deposited coatings were temperature annealed at ambient pressure and in some cases also at high pressure. The resulting microstructure was first evaluated through a combination of x-ray diffraction and transmission electron microscopy. In addition, mechanical properties such as hardness by nanoindentation were also reported. TiAlN coatings with two different compositions were deposited on polycrystalline boron nitride substrates and then high pressure high temperature treated in a BELT press at constant 5.35 GPa and at 1050 and 1300 °C for different times. For high pressure high temperature treated TiAlN it has been shown that the decomposition is slower at higher pressure compared to ambeint pressure and that no chemical interaction takes place between TiAlN and polycrystalline cubic boron nitride during the experiments. It is concluded that this film has the potential to protect a polycrystalline cubic boron nitride substrate during metal machining due to a high chemical integrity. TiZrAlN coatings with different predicted driving forces for spinodal decomposition were furthermore annealed at different temperatures. For this material system it has been shown that for Zr-poor compositions the tendency for phase separation between ZrN and AlN is strong at elevated temperatures and that after spinodal decomposition stable TiZrN is formed.

Full text
Abstract:
TiAlN/VN multilayers, with a layer periodicity of ~3nm, have exhibited superior sliding wear resistance (1.26xlO-17m3N-lm-l) and lower friction coefficient (~=0.4, pin-on-disc test, Ah03 ball counterpart) when compared to other commonly used wear protective coatings, e.g. TiN, TiAlN and TiAlN/CrN. They require excellent oxidation and wear resistance for dry high speed machining operations. This project investigates the microstructure of the as-deposited coatings, their oxidation degradation mechanism and their wear and friction properties at room and elevated temperatures. The microstructure of the starting films was studied in terms of intermixing between the TiAlN and VN individual layers caused by the absence of shutters during the industrial PVD deposition. A FEGTEM coupled with EELS revealed chemical distribution of individual layers at nanometre resolution. Cs corrected STEM allowed the composition of individual atomic columns to be imaged. It was also used to probe across the interface of TiAlN/VN with angstrom beam (1 A) using EELS which showed a 1±0.1 nm thick intermixing between TiAlN and VN. Film growth and elemental distributions were therefore theoretically predicted in association with substrate rotation. The experimental compositional profiles and the prediction showed good agreement. The coatings deposited with -75 V and -85 V substrate bias voltage were multilayer TiAlNNN, 37at%:::;V:::;55at%, 0.81:::;(Ti+Al)/V:::;1.73, which were used for subsequent oxidation and wear studies. The oxidation behaviour of these coatings in air was investigated using thermal gravimetric analysis up to 1000°C and compared to TiN and TiAlN. Static oxidation of TiAlN/VN films was studied in the range 550-700°C, and characterised by high temperature in-situ X-ray diffraction and STEM/EDXlEELS of selected surface cross-sections. The oxidation resistance of TiAlN/VN was found to be controlled by the VN layers and consequently oxidation was initiated at a lower temperature than TiN and TiAlN coatings. The onset for rapid oxidation of the TiAlN/VN coating was found to be 2550°C. At temperatures >600°C, a duplex oxide structure was formed; the inner layer comprised a porous region of Ti-rich and V-rich nanocrystallites, while several phases were observed in the outer region, including V20 5, Ti02 and AlV04. V20 5 was the dominant oxide at the outer layer at 2638°C. An Au marker study suggested roughly equal diffusivity of cations outward and oxygen inward diffusion occurred during oxidation. Further to the oxidation study, dry sliding ball-on-disc wear tests of TiAlN/VN (V 55.2at%, Ti 28.5at% and Al 16.3at%) coatings on flat stainless steel substrates were undertaken against Ah03 at 25°C, 300°C and 635°C in air to investigate the relation between the presence of V 205 and low friction. The friction coefficient was 0.53 at 25°C which increased to 1.03 at 300°C and decreased to 0.46 at 635°C. Detailed investigation of the worn surfaces was undertaken using site-specific TEM via FIB, along with FTIR and Raman spectroscopy. Microstructure and tribo-induced chemical reactions at these temperatures were correlated with the coating's wear and friction behaviour. The friction behaviour at room temperature is attributed to the presence of a thin hydrated tribofilm and the presence of V 205 at high temperature.

Abstract:
Hard coatings can extend the life time of a tool substantially and enable higher cutting speeds which increase the productivity in the cutting application. The aim with this thesis is to extend the understanding on how the microstructure and mechanical properties are affected by high temperatures similar to what a cutting tool can reach during operation. Thin films of ZrAlN and TiAlN have been deposited using cathodic arc-evaporation. The microstructure of as-deposited and annealed films has been studied using electron microscopy and x-ray scattering. The thermal stability has been characterized by calorimetry and thermogravity and the mechanical properties have been investigated by  nanoindentation. The microstructure of Zr1−xAlxN thin films was studied as a function of composition, deposition conditions, and annealing temperature. The structure was found to depend on the Al content where a low (x < 0.38) Al-content results in cubic-structured ZrAlN while for x > 0.70 the structure is hexagonal. For intermediate Al contents (0.38 < x < 0.70), a  nanocomposite structure with a mixture of cubic, hexagonal and amorphous phases is obtained. The cubic ZrAlN phase transforms by nucleation and growth of hexagonal AlN when annealed above 900 ◦C. Annealing of hexagonal ZrAlN thin films (x > 0.70) above 900 ◦C causes formation of AlN and ZrN rich domains within the hexagonal lattice. Annealing of nanocomposite ZrAlN thin films results in formation of cubic ZrN and hexagonal AlN. The transformation is initiated by nucleation and growth of cubic ZrN at temperatures of 1100 ◦C while the AlN-rich domains are still amorphous or nanocrystalline. Growth of hexagonal AlN is suppressed by the high nitrogen content of the films and takes place at annealing temperatures of 1400 ◦C. In the more well known TiAlN system, the initial stage of decomposition is spinodal with formation of cubic structured domains enriched in TiN and AlN. By a combination of in-situ xray scattering techniques during annealing and phase field simulations, both the microstructure that evolves during decomposition and the decomposition rate are found to depend on the composition. The results further show that early formation of hexagonal AlN domains during decomposition can cause formation of strains in the cubic TiAlN phase.

The three systems were found to exhibit age hardening upon annealing, by different mechanisms, into the superhard regime (≥30 GPa), as determined by a combination of electron microscopy, X-ray diffraction, atom probe tomography, erda, and nanoindentation tech- niques. TiSiCN forms nanocomposite films during growth by virtue of Si segregation to the surface of TiCN nanocrystallites while simultaneously pro- moting renucleation. Thus, the common columnar microstructure of TiCN and low-Si-content (≤5 at. %) TiSiN-films is replaced by a “feather-like” nanos- tructure in high-Si-content (≥10 at. %) TiSiCN films. The presence of C promotes the formation of this structure, and results in an accelerated age hardening beginning at temperatures as low as 700 °C. The thermal stability of the TiSiCN films is, however, decreased compared to the TiSiN system by the loss of Si and interdiffusion of substrate species; C was found to ex- acerbate these processes, which became active at 900 °C. The ZrAlN system forms a two-phase nanostructure during growth consisting of cubic ZrAlN and wurtzite ZrAlN. Upon annealing to 1100 °C, the c-Zr(Al)N portion of the films recovers and semicoherent brick-like w-(Zr)AlN structures are formed. Age hardening by 36 % was obtained before overageing sets in at 1200 °C. As-deposited and annealed solid solution Ti0.33Al0.67N thin films were characterized for the first time by atom probe tomography. The as-deposited film was found to be at the very initial stage of spinodal decomposition, which continued during annealing of the film at 900 °C for 2 h. N preferentially segregates to Al-rich domains in the annealed sample, causing a compositional variation between Ti-rich and Al-rich domains, to maintain the stoichiometry for the developing AlN phase. That effect also compensates for some of the coherency strain formed between cubic domains of TiN and AlN. Finally, a possible Kirkendall effect caused by an imbalance in the metal interdiffusion during the spinodal decomposition was discovered.

Abstract:
In order to improve solid particle erosion (SPE) resistance for steam turbine blades and nozzles, in corporation with Kobe Steel, Ltd., evaluation of hard coatings of TiN and TiAlN deposited by the Arc Ion Plating (AIP®) process was performed to verify applicability to an actual steam turbine. The results of high-temperature steam oxidation tests and room-temperature sand erosion tests showed that the TiAlN coating had high-temperature stability superior to that of the TiN coating, and erosion resistance far superior to that in the case of the conventional CrC thermal spray coating and boronizing treatment. High-temperature fatigue and creep tests showed that the characteristic strength of the blade material with the TiAlN coating was equal or superior to that of the base blade material. On the basis of the results of comprehensive evaluation, it was confirmed that the TiAlN hard coating has excellent applicability to an actual steam turbine and it was successfully applied to steam turbine blades of power plants in Japan.

Abstract:
The tribological influences of PVD-applied TiAlN coatings on the wear of cemented carbide inserts and the microstructure wear behaviors of the coated tools under dry and wet machining are investigated. The turning test was conducted with variable high cutting speeds ranging from 210 m/min to 410m/min. The analyses based on the experimental results lead to strong evidences that conventional coolant has a retarded effect on TiAlN coatings under high-speed machining. Microwear mechanisms identified in the tests through SEM micrographs include edge chipping, micro-abrasion, micro-fatigue, micro-thermal, and micro-attrition. These micro-structural variations of coatings provide structure-physical alterations as the measures for wear alert of TiAlN coated tool inserts under high speed machining of steels.

Abstract:
The main objective of the present work is to determine the performance of resharpened integral coated cemented carbide end milling tools. Tools as new and after they have been resharpened were tested, during machining of hard steel used in the mold and die industry. The coatings used were TiAlN and AlCrN. The cutting speed was varied, keeping the depth of cut, the cutting width and the feed per tooth constants. Tests were carried out dry. A 23 factorial design was used, considering the following factors (and levels): cutting speed (80 and 100 m / min), tool coating (TiAlN and AlCrN) and the tool condition (new and reground). The output parameter considered is the tool life (wear rate). At the end of the tool life the wear mechanisms were analyzed within a Scanning Electron Microscopy - SEM. The results showed that in general the AlCrN coated tools outperformed the TiAlN. The performance of resharpened tools was very similar to the new tools, and statistically there is no significant difference between their tool lives.
