    詳細內容

    電鍍就是利用電解原理在某些金屬表面上鍍上一薄層其它金屬或合金的過程,是利用電解作用使金屬或其它材料制件的表面附著一層金屬膜的工藝從而起到防止金屬氧化(如銹蝕),提高耐磨性、導電性、反光性、抗腐蝕性(硫酸銅等)及增進美觀等作用。不少硬幣的外層亦為電鍍。電鍍時,鍍層金屬或其他不溶性材料做陽極,待鍍的工件做陰極,鍍層金屬的陽離子在待鍍工件表面被還原形成鍍層。為排除其它陽離子的干擾,且使鍍層均勻、牢固,需用含鍍層金屬陽離子的溶液做電鍍液,以保持鍍層金屬陽離子的濃度不變。電鍍的目的是在基材上鍍上金屬鍍層,改變基材表面性質或尺寸。電鍍能增強金屬的抗腐蝕性(鍍層金屬多采用耐腐蝕的金屬)、增加硬度、防止磨耗、提高導電性、光滑性、耐熱性和表面美觀。色釉馬克杯.jpg陶瓷杯廣告杯定制logo.jpg
