Abstract:
The aim of the study was to analyze the superhard anti-wear diamond-like carbon coatings produced by Plasma Assisted Chemical Vapor Deposition (PACVD) and Physical Vapour Deposition (PVD). The a-C:H and a-C:H:W coatings were deposited on steel elements operating under friction conditions. The analysis involved comparing the tribological properties of coated metal elements with those of uncoated elements. It was essential to analyze how the coating composition and structure influence the tribological behaviour of elements under dry and lubrication friction conditions. The coating structure was analyzed by observing the topography of the surface and the cross-sections using an atomic force microscope (AFM) and a scanning electron microscope (SEM). The results were employed to determine the elemental composition and thickness of the coatings. The tribological tests were performed applying a ball-on-disc tribometer and using a pin-on-plate tribometer. The tribological properties were analyzed also in a micro scale using a microtribometer. Compared with the substrate material - steel, the diamond-like carbon coatings showed lower linear wear, lower friction coefficient and higher hardness.

Abstract:
In this study, the possibilities for the reduction of powder wall friction by different types of surface coatings on the wall material were investigated. Two conventional coatings, an ultra-high molecular weight polyethylene plate and an anti-friction varnish, were tested, together with a diamond-like carbon coating. It is the first time a diamond-like carbon coating has been researched with respect to powder wall friction reduction. The wall friction angles were measured with a ring-shear tester. The results showed that the conventional coatings did not really reduce wall friction in comparison to structural steel. In comparison to the stainless steel they even increased it. In contrast, the diamond-like carbon coating reduced wall friction significantly. These first results are very promising. However, more detailed investigations are required.

Abstract:
Abstract The combination of unique physicochemical, mechanical and tribological properties of diamond-like coatings determines the prospects for their use in critical friction units, including those operating in a rarefied atmosphere and vacuum. The properties of diamond-like carbon (DLC) coatings depend on the contribution of the sp2 and sp3 fractions of the carbon hybrid atomic electron orbitals. Modern methods of determining the graphite and diamond proportion in coatings are time-consuming and insufficiently accurate. In addition, the determination of the sp3/sp2 ratio is often difficult due to the displacement of the energy position of the C1s electron line. In this paper, the change in the chemical state of carbon over the thickness of a diamond-like coating is studied by X-ray photoelectron spectroscopy. Analysis of the carbon line fine structure of the differential graphite spectra (sp2 bonds) and diamond (sp3 bonds) allowed us to establish the parameter δ, which determines the ratio of the graphite and diamond components in the DLC coating. Profiling with Ar+ ions of the diamondlike coating surface showed that with an increase in the etching time, the proportion of amorphized carbon increases, which means that the antifriction properties increase with the abrasion of the coating. The obtained regularities allow us to predict changes in the tribological properties of DLC coatings during operation. Ion profiling also allows to determine the thickness of coatings with high accuracy.

Abstract:
In this study, the friction characteristics of a magneto-rheological fluid are examined with different surface process technologies such as polytetrafluoroethylene coatings and diamond-like carbon coatings by using a reciprocating friction tester. The friction characteristics of the magneto-rheological fluid are also examined with diamond-like carbon coatings at various temperatures. The substrate material (plate) used for coating with diamond-like carbon and polytetrafluoroethylene is aluminum (Al6061), which is widely used in engineering applications. The descending sequence of the coefficients of friction is Al6061 > diamond-like carbon > polytetrafluoroethylene. The surfaces are observed by scanning electron microscopy before and after the experiment. In addition, the chemical compositions of the worn surfaces were analyzed using energy-dispersive X-ray spectroscopy. By comparing the results, the friction characteristics of the magneto-rheological fluid are analyzed based on the different coating methods.

Abstract:
DLC coatings have attracted an enormous amount of interest for science and engineering applications. DLC occurs in several different kinds of amorphous carbon materials. Owing to the extensive diversity in their properties, DLC coatings find applications in mechanical, civil, aerospace, automobile, biomedical, marine, and several other manufacturing industries. The coating life of DLC is predominately influenced by its constituent elements and manufacturing techniques. Numerous researchers have performed multiple experiments to achieve a robust understanding of DLC coatings and their inherent capabilities to enhance the life of components. In this review, a wide range of DLC coatings and their classification, properties, and applications are presented. Their remarkable performance in various applications has made DLC coatings a promising alternative over traditional solitary-coating approaches.

Abstract:
The study investigates the wear of microcrystalline diamond (MCD) and diamond-like carbon (DLC) coatings. The MCD and DLC coatings were grown by plasma enhanced chemical vapor deposition (PECVD) method on WC-Co substrates. The sliding wear tests were performed on the ball-on-plate type of tribometer in reciprocating mode. The ball-cratering wear tests were carried out using Calo tester. The mechanical profilometer, optical and scanning electron microscopes (SEM) were used for investigation of the surface morphology of the wear scars. The wear of DLC coating is more intense in comparison to the MCD coating. In contrast to the MCD coating, no evidence of the DLC coating deflection was found.

Abstract:
A new type of smart sensor based on metal-containing diamond-like carbon (DLC) coatings is presented. DLC coatings are widely used as protective coatings to improve the surface properties of objective materials; for example, to increase hardness and chemical stability. With the addition of metal clusters into DLC coatings, electrical conduction appears to depend on the microstructure. Such coatings can be used in fabricating resistive sensors. In this paper, we present tungsten-containing DLC (W-DLC) as a possible strain sensor. The strain sensitivity is greatly affected by the deposition condition. We also fabricate a double-layered DLC/W-DLC coating. The double-layered structure is expected to be used as a smart coating having functionality as a sensor with a protective DLC overcoat.

Abstract:
The efficacy of combined diamond and diamond like carbon coatings, to allow for effective and efficient dry turning of aluminium alloy Al 6082, has been investigated. Optimised diamond and diamond-like carbon (DLC) coatings were combined and deposited onto a WC-Co insert using chemical vapour deposition (CVD) methods. DLC coatings were developed by testing the effects of bias voltage, deposition time and gas pressure. During the development of the DLC layer, the effects of substrate geometry and positioning in the deposition chamber were investigated. It was discovered that coating characteristics could vary significantly across the samples as a result of geometrical effects. This contradicted claims that, as plasma enhanced CVD is a non-line of sight deposition method, any variation in the coating due to geometry would be negligible. SEM analysis revealed coating thickness to increase by over 50%. AFM measurements showed coating roughness to increase by up to 30 times, whilst Raman spectroscopy highlighted a significant decrease in sp3 bonding. This variation in characteristics was seen, through the use of scratch testing, to translate into significantly reduced tribological performance. Friction was increased by 60% and critical load was only half of that of the coating applied to flat surface. The combined coatings were characterised and machining performance was evaluated. Coating characteristics were examined using SEM, AFM and Raman spectroscopy. Cutting trials designed to simulate the expected tool life were conducted. Micro and nano-crystalline diamond coatings, with and without an additional DLC layer were trialled along with a single layer DLC coating. Commercially available uncoated and TiN coating inserts of identical geometry were also trialled as a reference. The results showed that the addition of the DLC layer effectively reduced the roughness of the diamond, however, this did not translate into reduced adhesion of the aluminium to the cutting tip. It has been shown that for this particular machining scenario, a smoother coating effectively increased friction and adhesion of the workpiece material. The investigation has highlighted that due to the complex dynamics of material transfer effects in sliding, it cannot be assumed that a smoother surface layer will lead to improved tribological performance.

Abstract:
Magister Chirurgiae Dentium
Dental implants are artificial fixtures that are surgically inserted into the jaws to replace missing teeth. The success of dental implant treatment is dependent on achieving successful osseointegration (Branemark et al. 2001). Drills used for implant site preparation are made of different materials such as stainless steel (SS), zirconia and ceramic. Most of them do not have sufficient cutting efficiency and wear resistance (Oliveira et al. 2012). Recently diamond-like carbon coating (DLC) has been added as a drill coating to increase the cutting efficiency, increase wear resistance and drill hardness (Batista Mends et al. 2014).

Abstract:
The characteristics of coatings prepared by acetylene decomposition in nonself-sustained discharge with a plasma cathode have been studied. The initial energy of electrons injected into the plasma was 0,1 – 0,7 keV, energy of ions bombarding the coating was 0,1 – 0,7 keV and the pressure of Ar + C2H2 gas mixture was 0,2 – 1 Pa. Microhardness and wear resistance of coatings were measured by methods of kinetic indentation and ball abrasion. The coatings with high microhardness (40 – 60 GPa) and high wear resistance were deposited on conditions that ion energy exceeded 300 eV. It was shown that coating’s microhardness and internal stresses in the coatings deposited on chamber walls could be reduced by concerted change of voltage accelerating injected electrons and bias voltage applied to samples placed into the plasma. This allows to avoid delamination of coating particles from the walls and to provide high quality coating on samples.

Abstract:
L’utilisation d’un col modulaire lors de la pose d’une prothèse totale de hanche introduit une nouvelle interface, entre la tige et le col, qui est susceptible de s’endommager par fretting lors de la marche. L’alliage Ti–6Al–4V est très largement utilisé pour les tiges et les cols. Cependant, les contacts Ti–6Al–4V / Ti–6Al–4V présentent un frottement élevé et une forte usure adhésive dans les conditions de fretting. Les revêtements DLC (diamond-like carbon) ont été largement utilisés comme revêtements protecteurs pour les pièces métalliques. Ainsi, ils peuvent être introduits dans les contacts entre la tige en Ti–6Al–4V et le col en Ti–6Al–4V. L’objectif de cette thèse est d’étudier les comportements tribologiques du revêtement DLC et de l’alliage Ti–6Al–4V dans les conditions de fretting pour application au contact entre la tige et le col. Les essais de fretting sont menés avec un contact cylindre sur plan sous différentes valeurs d’amplitude de déplacement (± 20 μm, ± 40 μm, et ± 70 μm) et de force normale (entre 200 N et 1 200 N). En outre, les effets de différents revêtements (DLC A et DLC B), différentes rugosités de surface (lisse et rugueuse), différentes positions de revêtement (revêtement sur le plan, sur le cylindre et sur les deux surfaces), différents environnements (dans l’air et dans le sérum de veau) sont analysés. Par ailleurs, l'origine du faible frottement du contact entre Ti–6Al–4V et revêtement DLC est explorée. Les propriétés mécaniques du tribofilm formé sur la surface de Ti–6Al–4V frottée sont également étudiées.Pour les tests de fretting sans revêtement (contact Ti–6Al–4V / Ti–6Al–4V) dans l’air, le coefficient de frottement est élevé, entre 0.8 et 1.2. Le volume d’usure croît avec l’amplitude de déplacement. Pour les tests avec revêtement, le Ti–6Al–4V peut être bien protégé, sous des charges relativement faibles. Le coefficient de frottement (d’environ 0,2) et le volume usé sont faibles. Sous fortes charges, le revêtement est presque totalement éliminé. Le frottement et le volume d'usure sont similaires à ceux des essais sans revêtement. Le revêtement plus dur (DLC A) a de meilleures propriétés tribologiques que le DLC B. Le revêtement sur la surface lisse présente une meilleure performance en fretting que sur la surface rugueuse. Le revêtement sur une surface cylindrique présente une meilleure performance tribologique que sur une surface plane. Le revêtement DLC est plus endommagé lorsqu'il glisse contre un revêtement DLC que contre du Ti–6Al–4V non revêtu. Le revêtement fonctionne mieux en présence de sérum que dans l’air. Un tribofilm est formé sur la surface de Ti–6Al–4V frottée lorsqu'il glisse contre un revêtement DLC sous de faibles charges. Le tribofilm présente une dureté plus élevée, un module de Young plus élevé, un module de compression plus élevé, une limite d'élasticité plus élevé que l’alliage Ti–6Al–4V. Un modèle tribologique est proposé pour la formation du tribofilm et l'explication de l'origine du faible frottement, par une analyse approfondie des surfaces de contact, sur les points de vue mécaniques et chimiques
The use of modular neck adapter when placing a total hip prosthesis introduces a new interface, between the femoral stem and the neck adapter, which is propitious to fretting damage during walking. Ti–6Al–4V alloy has been widely used in neck adapters and femoral stems. However, the Ti–6Al–4V / Ti–6Al–4V contacts present high friction and severe adhesive wear under fretting conditions. Diamond-like carbon (DLC) coatings have been widely used as protective coatings for metallic parts. Thus, they can be introduced into Ti–6Al–4V neck adapter / Ti–6Al–4V femoral stem contacts.The objective of this thesis is to investigate the tribological behaviors of DLC coating and Ti–6Al–4V alloy under fretting conditions for application to neck adapter / femoral stem contact. Fretting tests are conducted with a cylinder / flat contact under different values of displacement amplitude (±20 µm, ±40 µm, and ±70 µm) and normal force (between 200 N and 1 200 N). Furthermore, the effects of different DLC coatings (DLC A and DLC B), different surface roughness (smooth and rough), different coating positions (coating on the flat, on the cylinder, and on both surfaces), different environments (laboratory air and calf serum) are analyzed. Besides, the origin of low friction of Ti–6Al–4V / DLC coating contact is explored. The mechanical properties of tribofilm formed on the rubbed Ti–6Al–4V surface is studied.For fretting tests without coating (Ti–6Al–4V / Ti–6Al–4V contact) under laboratory air condition, the friction coefficient is high, between 0.8 and 1.2. The wear volume increases with the displacement amplitude. For fretting tests with coating, Ti–6Al–4V can be well protected under relatively low load conditions. The friction coefficient is low (around 0.2) and the wear volume is small. Under high load conditions, the coating is almost totally removed. The friction and wear volume are similar to tests without coating. The harder coating (DLC A) has better tribological property than DLC B. The coating on the smooth surface exhibits better fretting performance than on the rough surface. Coating on a cylindrical surface shows better tribological performance than on a flat surface. The DLC coating is damaged more severely when it slides against a DLC coating than against the uncoated Ti–6Al–4V alloy. The coating performs better under the serum condition than under the laboratory air condition. A tribofilm is formed on the rubbed Ti–6Al–4V surface when sliding against a DLC coating under low load conditions. The tribofilm shows higher hardness, higher Young’s modulus, higher compression modulus, higher yield strength than the Ti–6Al–4V alloy. A tribological model is proposed for tribofilm formation and explanation of origin of low friction, by in-depth analysis of contact surfaces, on mechanical and chemical points of view

Abstract:
Les couches minces DLC (Diamond Like Carbon) ont fait l’objet depuis près de 25 ans de recherches principalement axées sur leurs propriétés tribologiques et leur optimisation. Ces couches minces sont maintenant matures (TRL 9) et reconnues pour leur très fort potentiel de réduction du frottement et de l’usure. Elles sont employées par de nombreuses industries : les DLC sont des solutions technologiques courantes pour réduire les frottements dans les moteurs de voitures de grande série (pièces de distribution, axe de piston...). De nombreuses études scientifiques ont aussi identifié la grande inertie chimique de ces couches à base de carbone et d’hydrogène dans des environnements liquides agressifs (acides ou basiques) et contenant des chlorures. Basé sur ces constatations, l’utilisation de matériaux à base de DLC, pour des applications tribologiques nécessitant aussi une bonne résistance à la corrosion des pièces revêtues, est envisagée. Dans la plupart des applications visées, les pièces sont faites d’aciers présentant de hautes propriétés mécaniques (ex. : 100Cr6 – acier à roulements) mais ayant souvent une résistance à la corrosion très faible.Dans un contexte industriel, l'évaluation de la protection contre la corrosion des films minces est menée, la plupart du temps, avec des tests de brouillard salin neutre. En laboratoire, elle est principalement effectuée à l'aide de techniques électrochimiques. Dans le cadre de cette thèse, les deux techniques ont été utilisées et adaptées pour une évaluation cohérente et répétable de la résistance à la corrosion d’aciers revêtus de couches minces à base de carbone.Une évaluation des couches minces DLC existantes d’Oerlikon Balzers sur acier 100Cr6 a été faite. Cette évaluation a été réalisée à l'aide d'essais en brouillard salin neutre et d’essais électrochimiques classique telles que des courbes de polarisation (avec mesure préalable du potentiel de circuit ouvert). La corrosion du substrat en acier revêtu s'est avérée être variable en fonction des solutions de revêtement DLC testées. Dans tous les cas, une faible résistance à la corrosion des éprouvettes revêtues a été détectée. L’origine de la corrosion d’acier revêtu de couche minces DLC a été étudiée. Les défauts dus aux procédés de dépôt des couches minces DLC se sont révélés être les principaux responsables de la mauvaise tenue à la corrosion des substrats revêtus. Pour étudier ces défauts, une nouvelle configuration électrochimique a été développée. Elle combine l’utilisation de séquence de polarisation avec des observations in situ de la surface. Cette méthode a permis le suivi des phénomènes de corrosion au niveau d’un unique défaut de taille micrométrique. Des défauts artificiels, de tailles micrométriques, ont été réalisés dans un revêtement DLC à l'aide d’une sonde ionique focalisée, plus connue sous le sigle anglais FIB (Focused ion beam) afin d’étudier les mécanismes de corrosion ainsi que la taille minimale des défauts susceptible de conduire à la dégradation par corrosion du substrat. Enfin, sur la base des défauts précédents et de leur étude, de nouvelles solutions de revêtements innovantes ont été développées et évaluées. Ces solutions sont divisées en trois parties basées sur des concepts de dépôts recensés par la littérature : une approche multicouches du dépôts, une approche par couplage galvanique favorable et pour finir une approche par ajout d’une couche barrière à la corrosion
Since almost 20 years, diamond-like carbon (DLC) thin films have been selected for tribological solutions mainly because of their excellent properties such as low coefficient of friction (five time less than bare steel in dry condition), high hardness (from 20 to 35 GPa for hydrogenated ones) and excellent wear properties (high abrasive wear resistance, preventing adhesive wear mechanisms). Most of the time, it has also been reported that DLC thin films have good intrinsic corrosion properties as they are chemically inert in sodium chloride solutions either in acid or basic environment. This has led to envision and evaluate the use of DLC thin films in tribological applications that also require complementary corrosion protection performances on coated parts (for instance: in aeronautic, in food industry for mechanical devices, in automotive for non-cosmetic part of structures). Typically, these coatings are deposited on steel alloys presenting high mechanical properties, such as tool steel or bearing ring steel that demonstrate poor or limited corrosion resistance.In an industrial context, the evaluation of corrosion protection of DLC thin films is presented, most of the time, with neutral salt spray tests or immersion tests, whereas at laboratory the evaluation would be mainly done using electrochemical techniques. In this work both techniques were used and also refined to specially fit the evaluation of such material. First, an evaluation of existing DLC based thin films from Oerlikon Balzers on mechanical steel were done as benchmark reference. This evaluation was conducted with NSS test and classic polarization experiments (open circuit voltage and linear sweep voltammetry). Corrosion of coated steel substrate was found to be variable depending on DLC coating solutions tested but, in all cases, a poor corrosion resistance of coated specimens was detected. Then origin of the poor corrosion protection aspect of DLC coating on steel substrate were studied. Defects coming from the deposition processes in coatings was found to be the main issues of poor corrosion results. To study such defects a new electrochemical setup was developed. It combines polarization experiments with in situ observations of a single defect at the surface. Artificial defects, with micrometric sizes, were milled in DLC coating using SEM-FIB to study the corrosion mechanisms as well as the minimum size of defects susceptible to lead to corrosion degradation. And finally based on the previous defects study, new and innovative coatings solutions were developed and evaluated. These solutions are divided in three parts based on coatings concepts found in literature: a multilayer approach, a galvanic coupling approach and a sealing layer approach

Abstract:
Companies that coat their products with DLC often have strict surface roughness and goals. This research investigates the surface roughness properties of uncoated and DLC coated specimens in an effort to know what uncoated surface roughness is needed to obtain a certain DLC coated surface roughness. Therefore, a model describing the relationship between uncoated and DLC coated surface roughness is needed. If this relationship can be estimated, the cost of surface finishing can be minimized by avoiding any unnecessary processes. A total of 7 specimens were tested before and after coating process with a non-contact surface roughness measurement microscope. Mathematical relationships are found between the DLC coated surface roughness and uncoated surface roughness. An experimental methodology was described for applying the findings to other coating methods and materials as the mathematical relationships found in this study are specific to the coating process and materials used.

Abstract:
Tungsten-doped diamond-like carbon (DLC) coatings have been magnetron sputtered onto 52100 steel with chromium and chromium/tungsten carbide dual interlayers using a Hauzer Techno Coating HTC 1200 4 UBM unbalanced magnetron deposition system. Internal fixturing to the deposition chamber rotates parts to be coated with a two degree of freedom system. By design, at certain intervals during the deposition, the acetylene flow is linearly altered to change film characteristics throughout the film. AES sputter depth profiling analysis shows that the fixture rotational system, designed to uniformly coat parts, causes localized chemistry variations in the coating. For a given location, the AES depth profile also clearly documents the intervals when acetylene flow was constant and when the flow was ramped.

Abstract:
Magnetron sputtered non-hydrogenated diamond-like carbon (DLC) coatings were tested against Al, Cu and Ti pins using a vacuum pin-on-disc tribometer. The objective was to compare Al, Ti, and Cu transfer to DLC coatings in air (29% RH) and an inert atmosphere (argon). In argon, a significant amount of adhesion and material transfer occurred from the Al and Ti pins to the DLC coating surfaces inflicting severe damage to the coatings. Wear and material transfer of the DLC coating against Cu were negligible in argon. Compared to tests in argon, the tribological performance of the DLC coatings against Al and Ti improved significantly in ambient air. In contrast, the wear rate of the DLC coatings against Cu was much higher in ambient air compared to that in argon.
