Abstract:

使用AMSLER摩擦磨损试验机进行摩擦磨损试验,研究超细羟基硅酸镁粉体作为润滑油添加剂在磨损后摩擦副表面的自修复特性。使用扫描电子显微镜、能谱仪和X射线光电子能谱分析了2种润滑油润滑下磨损后的45#钢环的表面形貌和化学组成。结果显示经50h纯润滑油润滑后在45#钢表面出现了大量的划痕,而之后经50h含添加剂润滑油润滑后这些划痕被自修复膜所覆盖。这层自修复膜主要由Fe,O,Si,C和Mg构成,这表明粉体添加剂在摩擦磨损过程中可以向磨损的金属表面发生转移。自修复膜的形成原理是这些粉体可以吸附到钢的磨损后新鲜表面,之后在接触表面的剪切应力下铺展于磨损后金属表面。这层自修复薄膜可以明显提高金属摩擦副的抗磨损性能。
