Kurzbeschreibung (Abstract)
The tribological behavior of an Al2O3/Al composite against a steel and an alumina was investigated in pin-on-disk wear tests using unlubricated conditions in air, Various composite compositions of aluminum contents ranging from 0 to 28 vol% mere investigated over a variety of contact loads and sliding speeds, Wear rate and friction force were continuously monitored during testing, Following completion of the test, pin weight loss and the profile of the wear tracks were determined, Scanning electron microscopy accompanied by EDAX analysis was used to investigate the worn surfaces and the wear debris, The wear behavior of the composites with a low metal content (<15%) during sliding against steel and alumina was found to be comparable to the wear of pure alumina, Wear occurred either on the steel or apparently simultaneously on the pin and alumina disk, With higher Al contents, wear shifts to the composite, the wear rate increases abruptly and is accompanied by fracture of the Al2O3 matrix, Wear appears to occur in the composite when the mechanical strain in the composite, near the contact surface, as a result of frictional loads, exceeds the fracture strain of the alumina matrix.
