In this paper, Al7075 alloy and 15 wt% VN/7075 composite were prepared by ball milling and hot-press sintering. The microstructure, hardness, and wear behavior under different working conditions (environmental condition: dry friction, sulfur-containing boundary lubrication, and oil lubrication) were studied. The results showed that the distribution of VN was dispersive and uniform in 15 wt% VN/7075 composite without obvious agglomeration. The hardness (119.5 Hv) of 15 wt% VN/7075 composite was 46.1% higher than the Al7075 alloy (81.8 Hv). Friction and wear behavior test results showed that under sulfur-containing boundary lubrication condition, according to the tribofilm layer on the worn surface of 15 wt% VN/7075 composite, the friction coefficient of 15 wt% VN/7075 composite decreased by 37.6% compared with the Al7075 alloy. The main wear mechanism of 15 wt% VN/7075 composite was delamination wear and abrasive wear under dry friction, while under sulfur-containing boundary lubrication and oil lubrication, it changed to mild abrasive wear.

Wide Usage

Due to its high mechanical strength, exceptional biocompatibility, low elastic modulus, and superior corrosion resistance, Ti13Nb13Zr alloy is one of the potential candidates for implanted joints. However, the poor tribological property of Ti13Nb13Zr alloy has greatly limited its wide usage in artificial joints. The elevated temperature solid carburizing technology was used to improve tribological property of Ti13Nb13Zr alloy. It was found that the surface hardness of Ti13Nb13Zr alloy was increased to 812 HV after the carburization at 1523 K due to the formation of titanium carbide on the surface. With the increase in experimental temperature, the thickness of the carburized layer increased to 120 μm. In addition, the wear rate of Ti13Nb13Zr alloy decreased by 63.9% under serum lubrication condition after the carburization at 1473 K due to the formation of hard TiC on the surface of Ti13Nb13Zr.

In the present study, the long-duration frictional and wear performance of the MCD/DLC (Micro-crystalline Diamond / Diamond-like Carbon) bilayered film are investigated under water-lubricating conditions. All friction tests are carried out on a rotation “ball-on-plate” tribotester where the MCD/DLC is slid against with a Φ 6.0 mm Si3N4ball and the whole sliding contact is immersed in deionized water during the sliding process. A full factorial experimental plan is conducted with four sliding velocities ranging from 0.126 to 0.503 m/s and four normal loads from 2 to 8 N. The duration of each sliding process is 24 h. For the sake of comparability, conventional MCD and NCD (nanocrystalline Diamond) films are also adopted under each sliding condition. The results show that the stable coefficient of friction (COF) of MCD/DLC film is ranging from 0.025 to 0.12 under the water-lubricating condition, comparable with the NCD film but much lower than that of single-layered MCD film; in contrast, the top-layered DLC film does not show beneficial effect on enhancing the sliding stability of single-layered diamond films. Moreover, its specific wear rate is estimated at the level of 10-8mm3N-1m-1, higher than that of MCD or NCD films. The sliding interface is under boundary lubrication condition, high normal load causes more prominent mechanical interactions between two contacted surfaces and thus produces a smoother and cleaner equilibrium sliding interface, which finally results in the decreasing tendency of stable COF as the load rises. Comparatively, the sliding velocity does not exhibit evident influence on the stable COF of the MCD/DLC film.
