“…The presence of a DLC coating was observed to improve the wear resistance of 316L stainless steel [11]. Significant reductions in the wear rates of 316L stainless steel coated with DLC in sliding contact with DLC coated 316L stainless steel [10] and UHMWPE [9] have been reported to such an extent that the low level of wear observed was comparable to that for ceramic femoral heads [9].…”

“…One area of considerable interest is biomedical applications, particularly orthopaedic applications, such as knee and hip joint replacements [1,2] where these properties combined with excellent biocompatibility make them extremely attractive candidates. The tribological behavior of these coatings has been studied when deposited on a range of biomaterial substrates to include Co-Cr alloys [1,[3][4][5][6][7], Ti alloys [8], stainless steels [9][10][11] and ultra high molecular weight polyethylene (UHMWPE) [12,13]. Significant reductions in the wear rates have been observed for DLC coated CoCr alloy in contact with UHMWPE [1,3,4] and CoCr alloy [6] compared with uncoated CoCr alloy which was observed to decrease with increasing film thickness [3,4].…”

Abstract:In this study diamond like carbon (DLC) coatings with Si interlayers were deposited on 316L stainless steel with varying gas pressure and substrate bias voltage using plasma enhanced chemical vapor deposition (PECVD) technology. Coating and interlayer thickness values were determined using X-ray photoelectron spectroscopy (XPS) which also revealed the presence of a gradient layer at the coating substrate interface. Coatings were evaluated in terms of the hardness, elastic modulus, wear behavior and adhesion. Deposition rate generally increased with increasing bias voltage and increasing gas pressure. At low working gas pressures, hardness and modulus of elasticity increased with increasing bias voltage. Reduced hardness and modulus of elasticity were observed at higher gas pressures. Increased adhesion was generally observed at lower bias voltages and higher gas pressures. All DLC coatings significantly improved the overall wear resistance of the base material. Lower wear rates were observed for coatings deposited with lower bias voltages. For coatings that showed wear tracks considerably deeper than the coating thickness but without spallation, the wear behavior was largely attributed to deformation of both the coating and substrate with some cracks at the wear track edges. This suggests that coatings deposited OPEN ACCESSCoatings 2014, 4 215 under certain conditions can exhibit ultra high flexible properties.

“…The relative atomic concentration of C 1s decreased from 69% to 44% after N 2 plasma treatment and to 38% after Ar plasma treatment, indicating that N 2 and Ar plasma treatments could remove the surface contaminants. 13 The work function increased about 0.55, 0.65, and 1.25 eV after N 2 , Ar, and O 2 plasma treatments, respectively. The relative atomic concentration of C 1s decreased from 69% to 37% and that of O 1s increased from 6% to 26%.…”

The application of Diamond-like-carbon coatings (DLC) to bearing surfaces is widespread from machining to bio-implants and has resulted in significant study of coating properties. The aim of this investigation was to determine the performance of two diamond-like-carbon coatings, using Chromium and Silicon as adhesion layers. Linear reciprocating wear tests were carried out at room temperature using an AISI 440C steel ball reciprocating against the DLC coated metal substrate. The performance of the coatings under different contact pressures (500 to 3000 MPa); peak sliding velocities (28 to 378 mm/s); and stroke length, (1.5 to 4 mm). An electric resistance measurement was used to monitor coating failure owing to the dielectric nature of the tested coatings.An increase in contact pressure resulted in a decrease in number of cycles to failure for both the coatings. However, the number of cycles to failure increased proportionally with sliding speed. In addition, artifacts on the coating and blister formation generated coating debris which acted as a third body during the wear process. The debris caused complete delamination of the coatings initially at the ends of the wear scar. The Silicon adhesion layer coating samples were found to provide a greater resistance to failure due to it being thicker, harder, and more elastic as compared to samples having a Chromium adhesion layer.
