摘　　要：为了研究驱动桥壳再制造沉积镀层的工艺性能,在40Mn基材的半轴套管表面采用电刷镀方法形成再制造修复层,选用线切割技术制备镀层和基体试样,分别利用金相显微镜观测了镀层和基体的微观形貌、采用硬度测试计验证了镀层和基体的硬度分布、使用X射线衍射仪进行了试样的物相分析。结果表明:在再制造沉积层的最大可镀范围内,镀层和基体结合可靠、镀层硬度优于基体、沉积镀层中未引入过多其它杂质元素,镀层性能可以满足再制造的使用性能要求。In order to study the process performance of the remanufactured deposited coating of the drive axle housing, the remanufactured repair layer was formed by brush plating on the surface of the half shaft sleeve of 40Mn substrate. The coating and substrate samples were prepared by wire cutting technology. The micro-morphology of the coating and substrate samples were observed by metallographic microscope, the hardness distribution of the samples was verified by hardness tester, and the phase analysis of the samples was carried out by X-ray diffractometer. The results show that within the maximum plating range of the remanufactured deposition layer, the combination of the coating and the substrate is reliable, the hardness of the coating is better than that of the substrate, and there are not too many other impurities in the deposited coating. The performance of the coating can meet the performance requirements of remanufacture.
