涂镀是在表面局部快速电沉积金属的新技术。涂镀层具有良好的机械性能,涂镀层与基体金属的连接强度比较好,工艺灵活,适用于碳钢、铸铁、合金钢、镍和一些铬、铝、钢及其合金。涂镀过程中工件的加热温度<70℃,不会引起变形和金相组织变化,涂镀层尺寸精确,采用安培——小时计监控涂镀层厚度,精度可达±0.01毫米,在要求不高的场合,不需要机械加工。涂镀能显著提高零部件的使用寿命和可靠性,提高设备的利用率,减少配件的
Plating is a new technique for rapidly electrodepositing metals locally on the surface. Coating with good mechanical properties, coating and base metal connection strength is relatively good, flexible process for carbon steel, cast iron, alloy steel, nickel and some chromium, aluminum, steel and its alloys. Workpiece coating temperature of <70 ℃, will not cause deformation and microstructure changes, coating size accuracy, the use of ampere-hour meter monitoring coating thickness, accuracy up to ± 0.01 mm, less demanding Occasion, do not need mechanical processing. Coating can significantly improve the service life of parts and reliability, improve equipment utilization, reduce the parts
