g/L，硼酸35 g/L，氯化鈉20g/L，HN-880C絡(luò)合劑20ml/L、HN-880B光亮劑2ml/L和HN-880A柔軟劑40ml/L。鑄鐵件的鍍后清洗非常重要。一般采用熱水和冷水交替清洗 2-3次，再進(jìn)行鈍化處理。熱水清洗時(shí)，可使?jié)B入鑄鐵孔隙的鍍液因受熱膨脹而溢出，用冷水清洗時(shí)恰好相反，即冷水進(jìn)入孔隙內(nèi)，可防止表面泛白。與其他基材電鍍鋅鎳合金一樣，鍍層必須經(jīng)過鈍化和封閉處理，以提高防腐性能，改善外觀，并獲得均勻的銀色、黑色等不同顏色。常見的電鍍鍍鋅鎳合金電鍍鋅鎳合金較主要的特點(diǎn)就是外表具有一定的美觀性。</p><div
