低温镀铁做为一种修复方法广泛应用于机械磨损部件或加工超差件的修复,取得了良好的经济效益与社会效益。该技术具有设备投资少、生产成本低、应用范围广、工艺稳定和镀层性能良好等特点。我们对其工艺特点、治化方式、镀层性能及镀层组织结构特点进行了研究,并取得了一些进展。经实践证明其经济效益良好。 Low-temperature iron plating as a repair method is widely used in mechanical wear parts or processing of ultra-poor parts of the repair, and achieved good economic and social benefits. The technology has less equipment investment, low production cost, wide range of applications, process stability and coating properties such as good. We have carried on the research to its craft characteristic, the method of treatment, the coating performance and the microstructure of the coating, and made some progress. The practice proved its good economic benefits.
