| 摘 要： | 采用真空熔炼的方法制备了CuAg-Zr合金，研究了微量Zr对Cu-Ag合金磨损行为的影响，探讨了合金的磨损机理．结果表明：Cu-Ag合金的磨损率随着Zr含量的增加明显减小，随着受电电流和滑动距离的增大逐渐增大．粘着磨损、磨粒磨损和电侵蚀磨损是主要的磨损机制．微量Zr的加入使合金中形成弥散细小的析出相，使其磨损性能明显优于Cu-Ag合金．

| Abstract: | Cu-Ag-Zr alloys are produced by means of a vacuum induction furnace. The effect of Zr addition on the wear behavior of Cu-Ag alloy and the wear mechanism had been investigated using wear property tests, scanning electron microscope (SEM), energy dispersive X-ray spectrum (EDS) and transmission electron microscopy. The results show that the wear rate of Cu-Ag alloy decreases with the increase of Zr content, the wear rate of the material increases with the increase of sliding distance and electrical current. Adhesive wear, abrasive wear and electrical erosion are the dominant mechanisms during the electrical sliding processes. Compared with the Cu-Ag alloy, the Cu-Ag-Zr alloy wire has much better wear resistance, which was caused by dispersed fine precipitates. |
