Abstract
Al2O3 fiber (Al2O3f) and SiC particle (SiCp) hybrid metal matrix composites (MMCs) were fabricated by squeeze casting method. The tests were carried out using a pin-on-disk friction and wear tester by sliding these pin specimens at a constant speed of 0.36 m/s (570 r/min) against a steel counter disk at room temperature, 100 °C and 150 °C, respectively. To observe the wear characteristics and investigate the wear mechanism, the morphologies of the worn surfaces and specific wear rate were analyzed by using scanning electron microscope (SEM) and Arrhenius plots. Moreover, the effects of fiber orientation and hybrid ratio were discussed.
