为了探究应力和滑动速度对高氮不锈轴承钢微动磨损性能的影响,采用SRV-IV微动磨损试验机进行了不同应力和不同滑动速度下的微动磨损试验,对摩擦因数和磨损率进行分析,并对磨斑形貌进行观察。结果表明:试验钢的摩擦因数随应力和滑动速度的增加而减小;磨损率随应力和滑动速度的增加而增加。随着pv值(表示轴承工况的严重程度)的增大,高氮不锈轴承钢的磨损机理由黏着磨损逐渐转变为磨粒磨损和塑性挤出磨损。
In order to investigate the effect of stress and sliding velocity on the fretting wear behavior of high nitrogen stainless steel, SRV-IV fretting wear tester was used to test the fretting wear under different stress and different sliding velocities. The friction coefficient and wear rate Analysis, and the morphology of the scar was observed. The results show that the friction coefficient of the test steel decreases with the increase of the stress and the sliding speed. The wear rate increases with the increase of the stress and the sliding speed. With the pv value (indicating the severity of the bearing conditions) increases, the wear mechanism of high nitrogen stainless bearing steel gradually changes from adhesive wear to abrasive wear and plastic extrusion wear.
