采用销盘试验机在水润滑和锂基脂+3%MoS2润滑条件下对17种方法处理的材料进行了对比试验。结果发现,被测试材料的磨损机理在水润滑条件下为犁沟、剥落和塑性涂抹3种,在锂基脂+3%MoS2润滑条件下主要是犁沟磨损。另外通过对耐磨性与硬度和磨损表面分形特征的关系进行分析,对磨损表面的分形维数和分形粗糙度参数进行计算,发现在水润滑条件下,当磨损机理为犁沟或者塑性涂抹时,材料的硬度与耐磨性有对应关系;而在剥落磨损时,耐磨性与材料的硬度无对应关系。耐磨性越好的材料,磨损表面的分维数值较大;耐磨性差的材料,磨损表面没有分形特征。
Seventeen methods were tested on a pin-plate tester under water-lubricated and lithium grease + 3% MoS2 lubrication conditions. The results show that the wear mechanism of the tested materials is furrow, peeling and plastic coating under the condition of water lubrication, and mainly furrow wear under the lubrication of lithium grease +3% MoS2. In addition, by analyzing the relationship between wear resistance and the fractal characteristics of hardness and wear surface, the fractal dimension and fractal roughness parameters of wear surface were calculated and found that under water lubrication conditions, when the wear mechanism is furrow or plastic smear , The hardness and wear resistance of the material has a corresponding relationship; while the flaking wear, wear resistance and hardness of the material does not correspond. Wear better the material, the fractal dimension of the wear surface larger; poor wear resistance of the material, there is no fractal surface wear characteristics.
