Abstract:
It has been recognized that the fatigue properties of metals are greatly affected by the surface condition. In steel parts a marked improvement in fatigue performance can result from the formation of hard layer on the surface. The processes commonly used for surface hardening are nitridig and carburizing. The reason for such improvement is attributed to the formation of compressive residual stresses in the hardened layer. Nitriding processes produce higher hardness, hence induces higher compressive residual stresses., which effectively increase fatigue performance. In this work, a mixture of (NH3 –H2 )) gas was used for nitriding fatigue specimens of En41 A steel. The effect of nitriding condition such as, temperature, ammonia content., nitriding time, hardness, microstructure and the depth of nitrided layer was investigated. The results from fatigue tests were discussed and related with the hardness and the nature of microstructure of nitrided layer. It was found that higher hardness without the formation of Iron-nitride layer ( white layer) gives better fatigue properties.

Abstract:
Nitriding treatment is well known as one of the corrosion protection methods for steels as well as a way to prevent wear and fatigue. Initially, salt bath nitrocarburizing was popular, but recently, gas nitriding, gas nitrocarburizing, plasma nitriding and so on have come to be used more often because of their superior nitriding ability. In the case of nitriding, only nitrogen (N) diffuses into the steel, but in the case of nitrocarburizing, both nitrogen and carbon (C) diffuse into the steel. General speaking, nitriding includes all the treatments mentioned above. The corrosion behavior of nitride carbon steels has been understood mainly by salt bath or gas nitrocarburizing treatments1)-4).However, recently, nitriding is mainly applied to parts for things such as automobiles which need protection from wear and fatigue, and is seldom used for parts which need corrosion resistance. The present paper is to remind researchers again that nitrided steels show good corrosion resistance.Therefore, the comparison of various thicknesses of nitride layers as well as the comparison between nitride layers on steel has been carried out in this examination, using the salt spray corrosion test method. The effect of oxidation treatment after nitriding was also investigated.

Abstract:
Alloying of corrosion-resistant austenitic steels with nitrogen is widely used in production to stabilize austenite and to improve the strength and other properties of the metal. The possibility of alloying titanium-containing steels with nitrogen by introducing nitrogen into the melt is not possible, as it causes formation of the coarse defects in steel during casting and solidification of the metal (twisting of the peel, large nitride inclusions, accumulations of nitrides, etc.). The method of high-temperature gas nitriding can be alternative to liquid-phase nitriding for alloying austenitic titanium-containing chromium-nickel steels with nitrogen in order to increase their strength properties. In this work, we investigated the possibility of increasing the strength characteristics of thin-sheet austenitic corrosion-resistant Cr – Ni – Ti (Kh18N12T type) steel, containing 1.5 % and 3 % of titanium, through the use of solid-phase high-temperature nitriding. The nitriding was carried out at a temperature of 1000 – 1100 °С in an atmosphere of pure nitrogen for 5 or 8 hours. The average mass fraction of nitrogen in the samples after nitriding for 5 hours was 0.6 % and 0.7 % for the steels with 1.5 and 3 % of titanium, respectively, and after nitriding for 8 hours – 0.8 % and 0.9 %. It was shown that high-temperature nitriding followed by annealing provides a significant (by 2 – 3 times) increase in the metal strength characteristics compared with the state before nitriding, but reduces the ductility. Ductility of the steel is restored during final processing. For Kh18N12Т type steel with 1.5 % of titanium, an increase in the yield strength is obtained – by 3.3 times (from 180 to 600 MPa), strength – by 1.8 times (from 540 to 970 MPa), with a relative elongation of 28 %. An additional increase in strength properties was not found for the steel with 3 % titanium. The obtained results show the possibility of obtaining thin-sheet titanium-containing high-nitrogen steel (or products from it, for example, thin-walled pipes) by applying solid-phase high-temperature nitriding.

Abstract:
The nitriding behavior of austenitic stainless steels (AISI 304 and 316) was studied by different cold work degree (0% (after heat treated), 10%, 20%, 30%, and 40%) before nitride processing. The microstructure, layer thickness, hardness, and chemical microcomposition were evaluated employing optical microscopy, Vickers hardness, and scanning electron microscopy techniques (WDS microanalysis). The initial cold work (previous plastic deformations) in both AISI 304 and 306 austenitic stainless steels does not show special influence in all applied nitriding kinetics (in layer thicknesses). The nitriding processes have formed two layers, one external layer formed by expanded austenite with high nitrogen content, followed by another thinner layer just below formed by expanded austenite with a high presence of carbon (back diffusion). An enhanced diffusion can be observed on AISI 304 steel comparing with AISI 316 steel (a nitrided layer thicker can be noticed in the AISI 304 steel). The mechanical strength of both steels after nitriding processes reveals significant hardness values, almost 1100 HV, on the nitrided layers.

Abstract:
Abstract Steel nitriding is a thermo-chemical process leading to surface hardening and improvement in fatigue properties. The process is strongly influenced by many different variables such as steel composition, nitrogen potential, temperature, time, and quenching media. In the present study, the influence of such parameters affecting physic-chemical and mechanical properties of nitride steels was evaluated. The aim was to streamline the process by numerical–experimental analysis allowing defining the optimal conditions for the success of the process. Input parameters–output results correlations were calculated through the employment of a multi-objective optimization software, modeFRONTIER (Esteco). The mechanical and microstructural results belonging to the nitriding process, performed with different processing conditions for various steels, are presented. The data were employed to obtain the analytical equations describing nitriding behavior as a function of nitriding parameters and steel composition. The obtained model was validated, through control designs, and optimized by taking into account physical and processing conditions. Highlights The paper shows the development of a model based on very broad experimental activity. The data were employed to provide a provisional tool for nitrided steel mechanical and microstructural behavior. A very good experimental–numerical correlation was found.

Abstract:
The authors have studied and clarified that ion nitriding was able to improve the fatigue properties of tool steel. Five kinds of ion nitriding methods (ion nitriding condition is different) were used in this study. The fatigue test had been performed using a rotating bending fatigue testing machine to investigate the effects of ion nitriding on fatigue properties of tool steel. The fractography was analyzed using a scanning electron microscope (SEM), and hardness distribution was also investigated using a microhardness tester. As a result, the fatigue strength and hardness of the ion nitrided specimen increased after ion nitriding processing. It is considered that the compressive residual stress which produced by ion nitriding processing in the layer reduced fatigue fracture, and the altered surface composition improved surface hardness. According to the results of the fatigue test, the optimal ion nitriding method on improving the fatigue limit of tool steel was determined. The hardness of the specimens remarkably increased after ion nitriding processing.

From the point of view of nitriding treatment(570°C), Cu precipitation is also occurred in the steel containing 1.3mass%Cu at this temperature. In this study, the behavior of nitriding in ultra low carbon steels containing Cr and/or Al and/or V are investigated. The following results are obtained : (1)After nitriding treatment the distribution of vickers hardness(Hv) differs in added nitriding element. (2)Profile of hardness in thickness is resulted from mainly precipitation hardening of nitride. (3)The high fatigue limit of nitrided steel is occurred by residual stress in vicinity of the surface. (4) Nitride precipitation is promoted by Cu precipitation that occurs in early stage of heat treatment.

Abstract:
Nitriding is as an effective technique applied for many years to improve the surface hardness and wear resistance of low carbon and tool steels [1]. In the case of stainless steels, increase of surface hardness and wear resistance accompany by a drop in corrosion resistance due to the precipitation of CrN. In this respect, many attempts have been made to modify the surfaces of austenitic stainless steels to increase their surface hardness and wear resistance without scarifying the corrosion resistance [2-6]. It is finally concluded that, nitriding at temperatures lower than conventional nitriding process (which is generally about 550°C) has potentiality to produce a nitrogen expanded austenite (also known as S-phase), on the surface without formation of CrN. Due to the superb properties of the S-phase, the low temperature nitrided austenitic stainless steels exhibit very high surface hardness, a good wear resistance, and more importantly, an excellent corrosion resistance. Recently some attempts have been made to apply low temperature nitriding to martensitic stainless steels, which are widely used in the industries of medicine, food, mold and other civil areas [7-9]. In these works, where nitriding has been conducted by plasma processes, superior surface hardness, along with excellent wear and corrosion resistances have been reported for AISI 410 and AISI 420 grade martensitic stainless steels. This work focuses on low temperature gas nitriding of AISI 420 grade martensitic stainless steel in a fluidized bed reactor. In this respect the microstructures, phase compositions, hardness, wear and corrosion behaviours of the original and nitrided martensitic stainless steels have been compared.

Abstract:
There is an interest in industry in cost reduction. Tool wear constitutes an important element in the cost of many metal working processes, not only because of the cost of the tool, but also because of the cost of machine downtime. Saltbath nitriding of high speed steel tools adds only about 1% to the cost of a finished tool, but has been found to confer benefits considerably in excess of this over a range of cutting conditions . A series of cutting tests is described, during which cutting forces and tool temperatures were recorded simultaneously using microcomputer based instrumentation developed at the Polytechnic as part of this study. The shear mechanism for tools with a nose radius is investigated, and methods for evaluating the primary shear plane area are proposed and discussed. The variation in primary shear plane area with chip flow angle is evaluated. The method for predicting chip flow angle from tool geometry is presented, and results from this analysis compared with experimental data . A method for predicting primary shear angle from tool geometry, force measurements and workpiece material properties is developed. A number of methods for measuring tool temperature are described . Temperature distributions obtained from finite element heat transfer analysis are presented, and a mechanism for the catastrophic failure of the toolnose is proposed. A range of cutting conditions is described, over which the performance of high speed steel cutting tools is enhaced by saltbath nitriding.

Abstract:
"Case hardening, a process which includes a wide variety of techniques, is used to improve the wear resistance, by diffusing carbon (carburization), nitrogen (nitriding) and/or boron (boriding) into the outer layer of the steel at high temperature, and then heat treating the surface layer to the desired hardness without affecting the softer, tough interior of the part. In this research, a nitrogen-hydrocarbon gas mixture was used as the process atmosphere for carburizing steels. It can offer a cost and part quality alternative to the conventional endothermic atmosphere and vacuum processes. It can hold the promise for matching the quality of work parts processed in vacuum furnace, i.e. eliminating the intergranular oxidation which normally occurs in the endogas atmosphere. The process control of nitrogen-hydrocarbon atmosphere is also investigated in the research. Modified shim stock method is used to measure the carbon pickup and constant carbon flux modeling tool is used afterwards to predict the carbon profile. With minimum modification, commercially available equipment or sensors can be used to monitor non-equilibrium process atmosphere. Gas nitriding was also studied. For nitriding, the kinetics of the nitriding process with hydrocarbon gases addition and electric arc discharge activation of the nitrogen diluted ammonia atmosphere were investigated. Prior to and during the nitriding, hydrocarbon gases were reacted with metal surface and removed oxidation layers, which can accelerate nitriding process. Overall, nitriding with this unique gas mixture provides an alternative to a long-hour pure ammonia nitriding with more efficient energy utilization. The main objective of this project is to develop the conventional, atmospheric-pressure, low-cost surface hardening treatments for the case hardening of carbon, alloy and stainless steel. The possibility of plasma activation of atmosphere and metal surface to shorten processing time and save energy and time is investigated in this research. The process atmosphere is safer, more efficient, less toxic and less flammable. "

Abstract:
This work is an experimental evaluation of the wear and friction of a high strength alloy steel (super-CMV (SCMV» in its as heat treated and plasma nitrided states under fretting conditions in air, at both ambient and elevated temperatures. In order to conduct the experimental programme, a new test rig and associated data processing and assessment capability was developed. Wearing couples in homogeneous and heterogeneous arrangements were tested to assess the effectiveness of the nitriding process as a fretting palliative-the heterogeneous mating is particularly representative of configurations found in aerospace transmission assemblies. A range of test conditions were examined with a line contact, including normal loads from 25 to 65Nmm-1, displacement amplitudes from 10 to 100 µm and temperatures from 24 to 450°C. At ambient temperatures, the wear behaviour was assessed using an energy-wear analysis, whereupon it was demonstrated that the wear volume was a linear function of the dissipated frictional energy (over the range of loading conditions) with a significant energy threshold before the onset of wear. Accordingly, the fretting wear over the full range of loading conditions could be described by a single wear rate and threshold value. The wear rate for homogeneous couples of nitrided super-CMV (SCMVN) was found to be 12 % lower than that for comparable SCMV pairings, although the lower threshold energy for the SCMVN case would lead to them suffering greater wear at < 2.5 kJ of dissipated energy (in the configuration examined). In heterogeneous couples, the harder SCMVN specimen was found to wear preferentially; while the SCMV specimen suffered severe plastic damage of the surface, a protective oxide debris bed was seen to form, which protected the underlying SCMV from wear and abraded the SCMVN specimen. At elevated temperatures, the tribology (of both SCMV and SCMVN) was dominated by the formation of a glaze-layer. The progressive formation of the glaze, with increasing temperature, led to a critical transition temperature (TT) above which a significant reduction in both the wear and friction of the materials was observed. For SCMV, after only a modest increase in temperature to 85 °C, the overall loss of material from the contact had become negative. At temperatures greater than 85°C, negative wear was maintained, with the coefficient of friction dropping monotonically until a slight minimum at 300°C. The behaviour for the SCMVN couples was very similar; the transition to negative wear occurred at a higher temperature of 150°C but the friction minimum was also found at 300°C. It is proposed that the changes in wear rate and friction coefficient were due to changes in the way that the oxide particles sintered to form a protective debris bed, with sintering of the oxide debris particles at these low temperatures being promoted by the nano-scale at which the oxide debris is formed.

Abstract:
The research is divided into four related sections of work. The first relates to the rim wall wear of the existing unlubricated steel, and polyethylene centre bearing components. Based on these findings, the second and third sections of work includes materials characterisation of alternative centre bearing surfaces - plasma nitrided molybdenum steel and stellite 6 laser clad layers, respectively. Finally, in the last section of work, the reciprocating pin-on-plate wear test method is used to evaluate the friction and wear of the existing and alternative centre bearing materials. The worn dimensions of the AISI 1053 steel, Hadfield steel, and polyethylene centre bearing components were determined. The wear of the high density polyethylene centre bowl liner was negligible. The rim wall wear of the unlubricated steel components was greatest in the longitudinal direction, whilst there was negligible wear in the lateral direction. The average wear depth rate for the AISI 1053 steel top centre was approximately twice that of the Hadfield steel centre bowl liner. The cross-sectional microhardness and microstructure of one worn AISI 1053 steel top centre and two worn Hadfield steel centre bowl liners were determined. The worn Hadfield steel centre bowl liners showed significant near surface work hardening. The wear mechanism for the AISI 1053 steel top centre was plastic strain accumulation in conjunction with low cycle fatigue. The quench and tempered AISI 4016 molybdenum steel samples were plasma nitrided at 450, 500, 550 and 580 C using 75% N2: 25% H2 mixture gas for 5 hours. The microstructures of the coatings were determined using optical microscopy, and scanning electron microscopy. The treated samples were characterised using x-ray diffraction and vi microhardness. The optimum condition for this material was achieved at the temperature of 500 0C. Stellite 6 multi-track layers were laser clad onto mild and AISI 4016 steel substrates with a continuous wave Nd:YAG laser at 1800 W laser source power using four different processing speeds: 600, 900, 1200, and 1500 mm/min. The laser power, defocused laser spot size, and powder feed rate were held constant. The clad samples were characterised using optical microscopy and scanning electron microscopy (SEM) in conjunction with energy dispersive spectroscopy (EDS). Microhardness profiles of the clad layers and heat affected zones were determined. For both substrates the optimum processing speed is between 600 and 900 mm/min. Wear testing of Hadfield pin - AISI 1053 steel plate, Hadfield pin - untreated AISI 4016 steel plate, HDPE pin – Hadfield steel plate, Hadfield pin - plasma nitrided AISI 4016 steel (500 °C) plate, and Hadfield pin – laser clad Stellite 6 (600 mm/min) plate material pairs was conducted using the pin-on-plate reciprocating wear test method. The wear test conditions provided a good simulation of the rim wall operating conditions for the Hadfield steel pin – plasma nitrided AISI 4016 steel (500 °C) plate and Hadfield steel pin – laser clad Stellite 6 (600 mm/min) plate material pairs. The Hadfield steel pin – nitrided AISI 4016 steel (500 °C) plate material pair had the lowest wear under these wear test conditions, whilst it’s co-efficient of friction of 0.57 would make it suitable for use in lightly loaded (50 ton wagon mass) 3-piece freight bogies.

Abstract:
In this study, an innovative process called nanocrystallization-assisted nitriding was used to process 4140 steels. First, a nanocrystalline surface layer was induced in 4140 steel by ultrasonic nanocrystal surface modification (UNSM). The abundant nanoscale grain boundaries provide micro-channels for efficient nitrogen diffusion during nitriding at relatively low temperature (450 °C) and short duration (4 hours). The samples were characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. The hardness and corrosion resistance were examined and compared for samples after different processing conditions. It has been demonstrated that the sample processed by nanocrystallization-assisted nitriding has much higher hardness and corrosion resistance compared with the samples processed by nitriding only.

Abstract:
The erosion behavior of plasma nitriding SUS304 stainless steel by molten lead-free solder was examined. Plasma nitriding treatment was conducted to the surface of SUS304 steel. The thickness of the nitriding layer was approximately 17 μm. The layer mainly consists of Fe4N, CrN and Cr2N. Erosion of nitriding SUS304 stainless steel was observed after erosion test with molten Sn-3Ag-0.5Cu (mass%) solder at 450°C for 100 h. On the basis of the result of microstructure observation, it was found that Sn diffusion into the nitrided layer occurred in non eroded area. The result shows that Sn diffusion into the nitrided layer induces erosion of plasma nitriding stainless steel.

Abstract:
Abstract Nitriding surface hardening is commonly used on steel components for high wear, fatigue and corrosion applications. Case hardening results from white layer formation and coherent alloy nitride precipitates in the diffusion zone. This paper evaluates the microstructure development in the nitrided case and its effects on the hardness in both the white layer and the substrate for two industry nitriding materials, Nitralloy 135M and AISI 4140. Computational thermodynamic calculations were used to identify the type and amount of stable alloy nitrides precipitation and helped explain the differences in the white layer hardness, degree of porosity at the surface, and the hardening effect within the substrate. Some initial insights toward designing nitriding alloys are shown.

Abstract:
Abstract Since plasma jets, which have been used as heat sources of thermal plasma spraying process, expand adiabatically under a low pressure environment, the plasma temperatures drastically fell down to 2000K at the nozzle out let at 30Pa chamber pressure. However, the plasma jets still had enough reactivity to form hard nitride layer on the surface of the titanium samples by only a few minutes treatment. In this study, in order to obtain useful information for the practical applications of this plasma as low temperature and high rate surface modification processes, nitriding of nitriding steel and carbon steel using supersonic expanding hydrogen/ nitrogen mixture plasma jets were carried out. Consequently, though surface hardening was occurred slightly in the case of carbon steel, surface hardening was obviously promoted in the case of nitriding steel. In both cases, surface hardening was promoted with increasing hydrogen flow rate and thermal damages of the samples due to heat transfer from plasma jets weren't observed. Besides, according to the results of wear testing, wear mass loss of nitrided samples were much lower than that of non-nitrided samples. From these results, this process was found to have a high potential even in the case of surface modification of steel materials.
