“…More recently, Liu et al investigated the tribological properties of TiN ceramic coatings with a specific focus on the effects of sliding balls on wear. 274 The researchers fabricated TiN bioinert ceramic coatings doped with graphene oxide nanosheets (GO). These coatings were intended to serve as self-lubricating phases on a titanium alloy known as Ti 6 Al 4 V. Doping in the coating resulted in enhanced wear resistance and decreased friction coefficients.…”

“…In the early research on joint contact, Brand 23 and Unsworth 24 proposed that the range of natural law joint contact stress is 0.1-2.0 MPa. In this study, based on the experiment conducted by Liu et al, 25 a load of 15 N was determined, and the contact area between the ball and the surface was obtained using a pressure sensitive film, resulting in a contact pressure of 0.834 MP. The parameters of wear experiment were as follows.…”

In this study, we have innovatively proposed a method of in-situ synthesized TiC hard phase to improve the surface mechanical properties of artificial joint materials (Ti6Al4V). In order to explore the optimum graphene oxide (GO) addition, GO/Ti6Al4V composite powders with different proportions (0, 0.5, 1.0, and 1.5 wt.%) were prepared. The homogeneously dispersed GO/Ti6Al4V composite powder was prepared on Ti6Al4V substrate by laser cladding technology. The microstructure, phase composition, and mechanical behavior of GO/Ti6Al4V composite coatings were studied by scanning electron microscope (SEM), optical microscope (OM), energy dispersive spectrometer (EDS), tribometer, hardness tester, and surface profiler. The results showed that the addition of GO could significantly improve the mechanical properties of TC4 substrate. During the preparation of the coating, the grain size of in-situ TiC phase was nanoscale and was distributed between acicular martensite, which played a critical role in enhancing the mechanical properties of the coating. The TiC phase distributed between acicular martensite refine the grain size of [Formula: see text] phase and improve the cutting resistance of the coating. Nevertheless, excessive GO decreased the fluidity of the molten pool, and micro holes tended to generate in the coating, which had a negative impact on the mechanical properties of the coating. At the GO content of 0.5 wt.%, the microhardness of the GO/Ti6Al4V coating was 1.325 times that of pure Ti6Al4V. Under the friction environment of simulated body fluid solution, the average friction coefficient was approximately 0.307 and the wear rate decreased to 3.5 × 10−7 mm3/N · m.

“…Among these techniques, PN is extensively used as a surface modification method capable of forming relatively thick, complex, adherent films with corrosion resistance [11][12][13]. TiN coating, in particular, exhibits good biocompatibility and holds promise for various applications in human implants [14]. However, in the harsh oral corrosion environment, a TiN protective layer alone cannot effectively prevent oral bacterial infection, consequently impacting its antibacterial activity.…”

TC4 alloy is widely used in dental implantation due to its excellent biocompatibility and low density. However, it is necessary to further improve the corrosion resistance and surface hardness of the titanium alloy to prevent surface damage that could result in the release of metal ions into the oral cavity, potentially affecting oral health. In this study, Ti-N-O layers were fabricated on the surface of TC4 alloy using a two-step hollow cathode plasma source oxynitriding technique. This resulted in the formation of TiN, Ti2N, TiO2, and nitrogen-stabilized α(N)-Ti phases on the TC4 alloy, forming a Ti-N-O modified layer. The microhardness of the samples treated with plasma oxynitriding (PNO) was found to be 300–400% higher than that of untreated (UN) samples. The experimental conditions were set at 520 °C, and the corrosion current density of the PNO sample was measured to be 7.65 × 10−8 A/cm2, which is two orders of magnitude lower than that of the UN sample. This indicates that the PNO-treated TC4 alloy exhibited significantly improved corrosion resistance in the artificial saliva solutions.
