【Abstract】 The effects of slide velocity and hardness match on the wear is studied using CuCrMo 4Cr9Si2 friction pair within 300℃ to 500℃. Tests show that the effect of slide velocity on wear is related to environmental temperature, and the hardness match of friction pair exists a best value, i.e. the hardness of CuCrMo is slightly lower than that of 4Cr9Si2更多还原
