摘要: 叙述了等离子喷涂碳化钨(WC)涂层与不同材料组成摩擦副的静摩擦性能.结果显示,摩擦副的静摩擦系数与偶件的表面粗糙度和显微硬度相关.与WC涂层配对的偶件材料的显微硬度越低,摩擦副的静摩擦系数越高;提高WC涂层的粗糙度以及降低与WC配对的偶件材料的粗糙度可有效地提高摩擦副的静摩擦系数.

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
