The wear characteristics of SUS304 and SUS316 stainless steels were evaluated at the rotation speeds of 100 m/s, 200 m/s, and 300 m/s under dry and wet conditions. The transition of friction-induced martensite occurred in wear-affected regions of two materials, regardless of the wear test conditions. The specific wear rates (W_s) of both stainless steels increase with increasing rotation speeds, regardless of the circumstances. Moreover, W_s of SUS304 and SUS316, obtained under dry conditions, is significantly higher than that of SUS304 and SUS316 obtained under wet conditions, respectively. This is because that the water film on the wet ring can act as a liquid lubricant between the ring and the block during the tests. After the wear tests, the hardness changes of both SUS304 and SUS316 are much higher under dry conditions, compared to those under wet conditions.

干湿条件下不锈钢的摩擦诱导马氏体相变和磨损性能

在干燥和潮湿条件下，分别以100 m / s，200 m / s和300 m / s的转速评估SUS304和SUS316不锈钢的磨损特性。不管磨损测试条件如何，在两种材料的受磨损影响区域中都会发生由摩擦引起的马氏体的转变。无论何种情况，两种不锈钢的比磨损率（W _s）都随转速的增加而增加。此外，W_小号在干燥条件下获得的SUS304和SUS316的比值分别明显高于在潮湿条件下获得的SUS304和SUS316的比值。这是因为在测试过程中，湿环上的水膜可以充当环和块之间的液体润滑剂。经过磨损测试，与潮湿条件相比，SUS304和SUS316在干燥条件下的硬度变化要高得多。
