在机械、冶金、矿山、水电、化工、运输、电子、航天和国防工业中。有大量的零部件由于使用中磨损或加工中超差而要修复。电弧堆焊、电镀、低温镀铁、热喷涂等都是其常用的工艺。然而由于这些工艺的局限性,有些零件不能修复,或很难修复。目前,涂镀技术的发展及其应用,在零部件 In the machinery, metallurgy, mining, hydropower, chemical, transportation, electronics, aerospace and defense industries. A large number of parts due to wear and tear during use or in the process of ultra-poor and to be repaired. Arc welding, electroplating, low-temperature iron plating, thermal spraying, etc. are all its common technology. However, due to the limitations of these processes, some parts can not be repaired or difficult to repair. At present, the development of coating technology and its application in parts
