摘要：

The friction and wear behavior of three uniaxial metal-matrix composites (graphite/Al, stainless steel/Al and Al2O3/Al-Li) were investigated. Unidirectional sliding tests' were conducted in the three principal orientations (longitudinal, transverse, and normal). The experimental results suggest that graphite/Al is a low-friction, low-wear composite. In contrast, stainless steel/Al is a high-friction, high-wear and highly anisotropic composite. Scanning electron microscopic observations of the worn surfaces revealed that in all three composites fiber pull-out was the predominant mechanism of wear in transverse sliding, and is the principal reason for wear anisotropy.
