测定了两种钴基非晶合金耐磨性随摩擦速度的变化．结果表明，无论是制备态还是摩擦时形成的氧化膜均能降低非晶合金的磨损系数．
The wear resistance of two cobalt-based amorphous alloys with different friction velocities was measured. The results show that the oxide film formed during both preparation and friction can reduce the wear coefficient of the amorphous alloy.
