Abstract The objective of this work is to identify the most influential parameters on the friction coefficient and wear rate, using the response surface method. The friction tests were carried out by adopting the methodology of complete planes 23at three factors ("D", "V" et "Py"), at two level for each factor. The results show a decrease in the wear rate when the three factors are at their highest level and a decrease in the friction coefficient when using minimum loads and speeds on important distances. In addition, the developed mathematical models make it possible to reveal a correlation between the test parameters and the responses studied in their studied domain. An evaluation of the volume parameters "Vmc" and "Vvv" was carried out. The morphology of the worn surface shows that the friction under a load of 1 N leads to the predominance of an abrasive wear mechanism, while a load of 10 N favors an adhesive wear mechanism, increasing the parameters "Vmc" and "Vvv" to the maximum.

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.

The tribological performance of Polyetherimide (PEI) composites filled with different Polytetrafluoroethylene (PTFE) content was comparatively evaluated on MM-200 test rig in block-on-ring configuration under dry friction condition. The microstructures of worn surfaces, fractured surfaces and wear mechanisms of the PEI composite were examined under scanning electron microscope (SEM). The variations of elastic modulus and surface hardness with variation in composition were also investigated. The results showed that under conditions of dry friction the PTFE can lower the friction coefficient and reduce wear of the PEI composites. When filled with 10 wt. % PTFE, the composite had the lowest wear rate. For PEI filled with 5wt. % PTFE the friction coefficient was about 0.3 and remained comparatively stable with increase of the PTFE content.

The NiCoCrAlY+WC12Co coating with high density was prepared on the surface of the magnesium alloy by cold spraying. Effects of the WC12Co content on the wear behavior of coating were studied. The results showed that, under the dry friction condition, the weightlessness of wear of the coating with 20%WC12Co was smallest. The weightlessness of wear of the coating with 10%WC12Co was worse than that with 20%WC12Co. However, the weightlessness of wear of the coating without any WC12Co was worst among the three coatings. After the frictional experiment for 20 minutes, the weightlessness of wear of coating without any WC12Co was 10mg. Compared with that of coatings with 10%WC12Co and 20%WC12Co, the weightlessness of wear was lower than 35% and 54%, respectively. Obviously, the coating with 20%WC12Co had the capacity of the weightlessness of wear resistance. Consequently, the more the coating with WC12Co was, the higher the capacity of the weightlessness of wear resistance was.
