Abstract

Cu51.36Cr48.64 alloy was treated at 940? for 15min under different pressures, the Cr phase in Cu51.36Cr48.64 alloy was observed by optical microscope, scanning electron microscope and transmission electron microscopy, and its mechanical and sliding wear properties were measured by means of nanoindenter and micro-hardness tester, the effects of high pressure heat treatment on mechanical and sliding wear properties of Cr phase in Cu51.36Cr48.64 alloy were investigated. The results show that high pressure heat treatment can enhance the compactness of Cr phase, increase its hardness and elastic modulus, when the pressure was over 3GPa, the hardness of Cr phase increase slightly with the increase of pressure. Meanwhile, high pressure heat treatment can also decrease its friction coefficient.
