Friction Behavior of Plasma Sprayed Tungsten Carbide Coatings

Abstract

Abstract: The coefficient of static friction of friction pairs, which were composed of plasma sprayed tungsten
carbide coating and aluminium alloy, titanium alloy and plasma sprayed titanium coatings, respectively, were examined. The results obtained show
that surface roughness and hardness of friction pairs are important to the coefficient of static friction. The lower the hardness of contact
material against WC coating, the higher the static friction coefficient of a pair. The roughening WC coating and the smoothing pair material against
WC are useful for improving the static friction coefficient of the wear pair.

Key words: static friction, plasma spraying, tungsten carbide
