詳細說明

電鍍設備--電鍍: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。可以起到防止腐蝕,提高耐磨性、導電性、反光性及增進美觀等作用。

 

電鍍的概念

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。電鍍時,鍍層金屬做陽極,被氧化成陽離子進入電鍍液;待鍍的金屬制品做陰極,鍍層金屬的陽離子在金屬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、潤滑性、耐熱性、和表面美觀。
