摘　　要：[目的]某耐磨镀铬零部件长期依赖进口,在服役过程中会出现磨损、腐蚀等问题,对其进行修复再制造不仅符合绿色制造的理念,更可以大幅降低设备的运维成本,减少材料消耗。[方法]使用电刷镀铬技术对该零部件进行修复,对比了修复件和全新件表面Cr镀层的微观组织、表面粗糙度、显微硬度、耐磨性及耐蚀性,以探究电刷镀铬修复用于该零件的可行性。[结果]修复件的Cr镀层为光亮的银灰色,其微观形貌、显微硬度、表面粗糙度和耐蚀性都与全新件的Cr镀层相近,耐磨性则更优。[结论]电刷镀铬可用于修复该类零件,本文的研究结果有助于提高相应设备的国产化程度。[Introduction]A wear-resistant chromium-plated part is dependent on imports for a long time and is confronted with wear and corrosion problems during service.Repair and remanufacturing of the part not only conforms to the concept of green manufacturing,but also can greatly reduce the operation and maintenance costs of the corresponding equipment and the consumption of materials.[Method]The part was repaired by electrobrush plating with chromium.The microstructure,surface roughness,microhardness,wear resistance,and corrosion resistance of Cr coatings on the repaired part and the new part were compared to explore the feasibility of electrobrush Cr plating for repairing the part.[Result]The Cr coating on the repaired part was brightly silver-gray,and its micromorphology,
