Analysis of lubricant retention property and tribological property of C/SiC composite material

Abstract

Composite materials have attracted more and more attention because of their special properties. However, the tribological properties of the composite material still need further study because of their complex structure and many influencing factors. In order to compare the influence of friction pair on the tribological property and lubricant retention property of C/SiC composite material, the tribological properties of C/SiC composite material sliding against 45# steel and ZrO2 are studied based on pin on disc test method. The wear surface of C/SiC composite material is characterized by 3D profiler. The lubricant retention property is investigated based on the 3D surface topography. The result shows that C/SiC composite material wears heavily when sliding against 45# steel and the lubricant retention properties decreases dramatically. C/SiC composite material exhibits low friction coefficient and wear when sliding against ZrO2 material, and the wear surface has good load-carrying property and lubricant retention property, which indicates that C/SiC composite material and ZrO2 are good friction pair. The research result provides strong support to boarding the application and revealing the tribological properties of C/SiC composite material.
