Coatings such as diamond-like carbon (DLC) and titanium nitride (TiN) are employed in joint implants due to their excellent tribological properties. Recently, graphite-like carbon (GLC) and tantalum (Ta) have been proven to have good potential as coating as they possess mechanical properties similar to bones—high hardness and high flexibility. The purpose of this systematic literature review is to summarize the coating techniques of these four materials in order to compare their mechanical properties and tribological outcomes. Eighteen studies published between January 2000 and February 2013 have met the inclusion criteria for this review. Details of their fabrication parameters, material and mechanical properties along with the tribological outcomes, such as friction and wear rate, were identified and are presented in a systematic way. Although experiment conditions varied, we conclude that Ta has the lowest wear rate compared to DLC, GLC and TiN because it has a lower wear rate with high contact pressure as well as higher hardness to elasticity ratio. However, a further tribology test is needed in an environment which replicates artificial joints to confirm the acceptability of these findings.

“…A similar result was also obtained by Abreu et al [27,28] for NCD films under self mated conditions at macrotribology range. Schneider et al [64] reported a friction coefficient in the range of 0.2 when a 100Cr6 steel balls were made to reciprocate against nanocrystalline diamond film in the presence of a synthetic lubricant. Similar values of the friction coefficient were noted by them with WC-Co hardmetal as counter-body.…”

“…1 2 Therefore, several potential applications can be anticipated in many fields that include tribology, electronics, optics and electrochemistry. [3][4][5][6] Majority of these applications require an adherent diamond thin film deposited on non-diamond substrates. Among various substrates, diamond thin films on non-carbide-forming metals such as copper (Cu) have always had a large research potential because of the technological importance of copper as a substrate as well as its extensive use in microelectronics devices.…”

Diamond thin films on non-carbide-forming metals such as copper have always had a large research potential because of the technological importance of copper as a substrate as well as its extensive use in microelectronic devices. However, the inability of copper to form carbides as well as the large mismatch in thermal expansion coefficients result in the generation of very high stresses in the coating that lead to delamination, film cracking, or other deleterious effects. We report on a method to increase the adherence of diamond coatings on copper substrates based on a surface modification process. A copper substrate is sandblasted in order to increase the surface roughness and surface area considerably. This process is expected to enhance the mechanical interlocking between the substrate and diamond film and has increased the seed density and surface energy as well. Microcrystalline diamond thin films were deposited on sandblasted copper substrates using hot filament chemical vapor deposition technique. Adhesion property of diamond coatings was evaluated by thermal quench technique combined with Raman spectroscopy.
