Development and testing of Al-SiC and Al-TiC composite materials for application in friction units of oil-production equipment

Abstract

The results of laboratory and development wear tests of Al-based composite materials reinforced with TiC or SiC particles under dry sliding friction conditions are presented. It is shown that composite materials reinforced with TiC have better tribotechnical properties (friction coefficient, wear rate, wear coefficient, stability coefficient) as well as wear resistance. On the basis of the friction surface and wear debris investigations, the mechanisms of wear of the composite materials are determined.
