本文简要报道了微动振幅、循环数和负荷对分别经860C退火、激光相变硬化和激光熔凝渗碳处理的2Cr13不锈钢微动摩擦磨损性能之影响的研究结果。文章指出,这3种微动参量的增大都使微动磨损体积增大,但其对微动摩擦系数的影响却比较复杂:摩擦系数随循环数的增加先是急剧增大,然后增大速度明显减缓并逐渐趋于稳定;摩擦系数随负荷的增加而下降,其在负荷增至80N时达到最低点,然后又随负荷的增加面缓慢上升;微动振幅的增大对摩擦系数基本没有影响。
In this paper, the results of fretting amplitude, cycle number and load on the fretting friction performance of 2Cr13 stainless steel treated by 860C annealing, laser phase transformation hardening and laser carburizing carburizing were briefly reported. The article points out that the increase of these three kinds of fretting parameters increases the volume of fretting wear, but its influence on the fretting friction coefficient is rather complicated: the friction coefficient increases sharply with the increase of the number of cycles and then increases obviously Slowed down and gradually stabilized. The friction coefficient decreased with the increase of load. When the load increased to 80N, it reached the lowest point and then slowly increased with the increase of load. The increase of fretting amplitude had no effect on the friction coefficient.
