Wear behaviour of alumina plasma-sprayed coating on an AlCu alloy (original) (raw)

Abstract

fuming oxide was plasma sprayed on the surface of Al+% Cu ahoy substrate. The mo~holo~ of the coating was studied thoroughly using optical and scanning electron microscopy. The abrasive wear behaviour of the alumina coating was examined using the disk on disk method (Taber abraser). The wear rate of the coating was higher at the beginning of the wear tests and depended on the applied load. A linear relationship was observed between the wear rate and the initial surface roughness of the
