摘　　要：用不同添加剂和在不同试验条件下,对摩擦表面残余应力的影响进行了考察,结果表明:所有磨斑表面均为残余压应力,添加剂对残余应力有明显的影响,试验条件(时间和负荷)变化的初期,残余应力的变化最大,然后呈周期性变化。The effect of additive and experimental condition on residual compressive stress was reviewed. The result shows that all friction surfaces have residual compressive stress. Additive affects residual compressive stress obviously. At initial stages of the experimental condition variety, the ratio of residual compressive stress is maximum, then it takes on periodicity.
