“…It can be attributed to TiC coating formed on the carburised alloys' surface having higher hardness, which can improve the load-bearing capacity. Besides, the surface of carburised alloys has a microcellular structure, and it can store the lubricant and form a lubricating layer, thus reducing the friction coefficient [27]. The friction coefficient of the specimens can be classified into three conditions.…”

Ti15Mo alloy has been regarded as one of the most potential biomedical materials due to its excellent performance. However, the low hardness and poor wear resistance of titanium alloy limit the further application. Therefore, high temperature solid carburising technology was performed on the surface of Ti15Mo alloys to prepare titanium carbide (TiC) coating with graphene (G) as the carburising agent. The microstructure, mechanical properties, and tribological properties of TiC coating under different lubricants were investigated. Results showed that TiC coating was closely bonded to the titanium substrate. The maximum thickness of TiC coating treated with 1150°C was approximately 184.02 μm, and the microhardness of alloys treated with 1100°C can achieve 1221.5 HV. All modified Ti15Mo alloys showed improved tribological performance compared to the original samples. The wear mechanisms of modified Ti15Mo alloys were abrasive wear and adhesive wear under the SBF lubricant, and the TiC coating was slightly peeled off. The overall friction coefficient and wear rate under 25% calf serum lubricant were lower than the SBF lubricant, and surface scratches were almost absent, and slight abrasive wear and adhesive wear occurred on the surface.

“…However, there are enough counterexamples demonstrating materials with reduced hardness have a lower wear rate. For instance, while examining AlTiN-DLC (diamond-like carbon, DLC) coating [ 11 ] it was concluded that softer coating exhibits a lower wear rate due to carbon formation on the friction surface. In [ 12 ], wear and hardness reduction of superhard coatings based on boron carbides and nitrides appeared after the addition of graphite and molybdenum disulfide.…”

Potential relations of tribological characteristics of aluminum antifriction alloys with their compositions and mechanical properties were investigated. In this regard, the properties of eight aluminum alloys containing tin from 5.4% to 11% doped with lead, copper, silicon, zinc, magnesium, and titanium were studied. Mechanical properties such as hardness, strength, relative extension, and impact strength were analyzed. Within the tribological tests seizure load and wear of material were evaluated and secondary structures were studied afterwards. The absence of a definitive correlation between tribological behavior and mechanical properties was shown. It was determined that doping tin over 6% is excessive. The seizure load of the alloys increases with the magnesium content. Secondary structures of the alloys with higher wear rates contain one order less magnesium and tin.
