对制备的Cu-Cr析出强化型铜合金在电磨损试验机上进行磨损试验,并用扫描电子显微镜观察材料的磨损表面形貌,用能谱仪对其磨损表面主要元素进行分析,然后探讨其磨损机制。结果表明,Cu-Cr合金的磨损率随滑行距离的增加而增加;磨损率随Cr含量的增加而减小,其中Cu-0.65Cr、Cu-0.76Cr合金的磨损率是Cu-0.86Cr合金磨损率的2~3倍;Cu-Cr合金的磨损机制以粘着磨损为主。
The prepared Cu-Cr precipitation strengthened copper alloy was subjected to a wear test on an electric abrasion testing machine. The wear surface morphology of the material was observed by a scanning electron microscope, and the main elements of the wear surface were analyzed by an energy dispersive spectrometer. Then, the wear mechanism . The results show that the wear rate of Cu-Cr alloy increases with the increase of sliding distance, and the wear rate decreases with the increase of Cr content. The wear rate of Cu-0.65Cr and Cu-0.76Cr alloy is Cu-0.86Cr alloy wear Rate of 2 to 3 times; Cu-Cr alloy wear mechanism sticky wear-based.
