電鍍(du)是一種金屬表面覆(fu)蓋工(gong)藝，通過電解作用(yong)在基材(cai)上沉積一層薄薄的(de)、均(jun)勻的(de)涂層。它可以增加物體(ti)的(de)美觀程度和耐用(yong)性同時還可以保護(hu)內部材(cai)料不受腐蝕(shi)或磨損(sun)的(de)影響(xiang)而(er)破壞(huai)[1]。應用(yong)領域(yu)十分(fen)廣泛(fan)：包括建筑裝飾品(pin)（如(ru)樓梯扶手(shou)等(deng)）、日(ri)常(chang)用(yong)品(pin)以及工(gong)業(ye)產(chan)品(pin)等(deng)等(deng)；同時在電子(zi)行業(ye)也廣泛(fan)應用(yong)，比如(ru)制造電子(zi)產(chan)品(pin)中(zhong)使用(yong)的(de)彈簧器(qi)皿(min)及零部件。“我(wo)們日(ri)常(chang)生(sheng)活中(zhong)接觸到(dao)的(de)手(shou)機殼也是用(yong)電泳(yong)進行噴漆(qi)加工(gong)制作的(de)。”
