Abstract
Friction and wear behaviors of PEEK composite and white metal are studied using blocks on a ring wear tester under oil-lubricated conditions. Two kinds of block materials are tested: PEEK composite filled with 30 mass% of carbon fiber and white metal (WJ2). The ring is made of forged steel (SF540A). The sliding velocity is 15 m/s. The load varies between 294 and 1177 N. The ring temperature is measured with an alumel-chromel thermocouple with a diameter of 0.5 mm, located 1mm below the frictional surface. Results indicates that the PEEK composite has better seizure-resistant properties than the white metal. Wear scars on these materials are observed using a scanning electron microscope (SEM). The seizure mechanisms are then discussed.
