Abstract
The unrubbed and rubbed pin surfaces and the transfer film of nylon-15%CuS-30%CF composite formed on the steel disk surface were studied by X-ray photoelectron spectroscopy, secondary ion mass spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy (EDS). These studies revealed that CuS and nylon decomposed during rubbing and produced Cu, (CH 3) 2SO-CH 2-CH 2- and -CH 2-CH 2-COON groups, CUSSO 3, Fe 2(SO 4) 3 and FeSO 4. The analyses at different depths in the transfer film indicated higher concentrations of these species closer to the top surface of the transfer film than underneath. The EDS elemental map analyses on the unrubbed and rubbed nylon-35%CuS, and rubbed nylon-15%CuS-30%CF pin surfaces indicated that in the absence of fibers CuS spread over almost the entire contact surface but this did not occur when fibers were present. These results have been used to understand the wear mechanism in a polymer composite with both the filler and the fiber.
