摘　　要：利用在标准Sargent镀Cr电解液中添加Na_2MoO_4的方法,制备了Mo含量小于10%(重量比)的Cr-Mo合金镀层,讨论了镀液组成及工艺参数对镀层的成分、电流效率及其显微硬度的影响.并利用电子探针(EPMA)、X-射结衍射仪(XRD)、扫描电镜(SEM)等,对Cr-Mo合金镀层的成分、微观结构及表面形貌进行了分析.作者还在SRV试验机上测试了Cr-Mo合金镀层的抗微动磨损性能.The micro-structure of Cr-Mo alloy coatings is dependent upon the Mo content. The Cr-Mo coating with the Mo content about 0. 9% has the best fretting wear-resistance behavior and its wear-resistance volume is twice as much as that of Cr coating. Morover, the method of calculating the fretting wear volume of the coatings has been discussed in detail.
