用GCr15的球试样和 4 5 #钢平面试样在 2 0 0N的法向力作用下对大范围位移幅值下的往复滑动作了大量磨损试验。着重对摩擦系数、磨损系数、平面试样磨痕的表面形貌以及磨屑的尺寸和分布情况进行分析研究。结果表明 ,在本试验条件下 ,过渡区范围是 75～ 12 5 μm。过渡区和微动、滑动状态下的磨损系数、磨痕形貌以及磨屑的尺寸和分布均有所差异。
A large number of wear tests were performed on the reciprocating sliding at a wide range of displacement amplitude with GCr15 ball sample and 4 5 # steel plane sample under the normal force of 200N. Focuses on the friction coefficient, wear coefficient, surface morphology of the surface of the sample wear marks and wear debris size and distribution analysis. The results show that under the experimental conditions, the transition range is 75 ~ 125 μm. The transition zone and fretting, sliding wear coefficient, wear scar morphology and wear debris size and distribution are different.
