Abstract
Effects of sliding velocity and normal load on reciprocating wear behavior of SiC particle reinforced aluminum composites (matrix material : 2024Al; particle diameter : 5,20μm; volume fraction of particle (Vf) : 5%, designated as MMCp) were investigated using a reciprocating wear tester. MMCp specimens (plate) were rubbed against bearing steel SUJ2 (pin) at 1-9N and 5-15mm/s. The specific wear rate of MMCp at d=5μm increased with increasing sliding velocity and normal load. On the other hand, at d=20μm did not increase regardless of increasing sliding velocity and normal load. From the analysis of wear data and detailed examination of worn surface and wear debris, wear behavior is different between d=5μm and d=20μm.
