Repair of a wear-resistant part by electrobrush plating with chromium
[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, microhardness, surface roughness, and corrosion resistance were comparable to those of the Cr coating on the new part, while the wear resistance of the former was better than that of the latter. [Conclusion] It is feasible to repair the part by electrobrush plating with chromium. The research results of this paper also help to improve the localization of the corresponding equipment.
