style="text-indent:25px">電鍍鋅鎳合金溶液溫度當(dāng)其它條件不變時，升高溶液的溫度，通常會加快陰極反應(yīng)速度和離子擴(kuò)散速度，降低陰極極化作用，因而也會使鍍層結(jié)晶變粗。但是不能認(rèn)為升高溶液溫度都是不利的，如果同其它工藝條件配合恰當(dāng)，升高溶液溫度也會取得良好效果。例如升高溫度可以提高允許的陰極電流密度的上限值，陰極電流密度的增加會增大陰極極化作用，以彌補(bǔ)升溫的不足，這樣不但不會使鍍層結(jié)晶變粗而且會加快沉積速度，提高生產(chǎn)效率。此外還可提高溶液的導(dǎo)電性、促進(jìn)陽極溶解、提高陰極電流效率（鍍鉻除外）、減少***、降低鍍層內(nèi)應(yīng)力等效果。</p><p style="text-indent:25px">做好零件的前處理，是整個電鍍鋅鎳合金工序獲得良好結(jié)果的先決條件。必須保證除油和酸洗溶液的濃度和純度，溶液中漂浮的油污要及時清理干凈;其次，除銹液雜質(zhì)達(dá)到一定量時，將會影響鍍層質(zhì)量，所以要定期更換。在電鍍鋅鎳合金生產(chǎn)中，由于各種原因，導(dǎo)致各種有害雜質(zhì)進(jìn)入電鍍液。雜質(zhì)的種類繁多，大致有金屬雜質(zhì)、金屬氧化物、非金屬雜質(zhì)和種種不溶性懸浮物、有機(jī)雜質(zhì)等。各種鍍液所含雜質(zhì)的種類不盡相同，對同一種雜質(zhì)的容忍程度也不相同。鋅鎳合金電鍍后也要進(jìn)行鉻酸鹽鈍化處理，使其表面生成一層穩(wěn)定性高、組織致密的鈍化膜。</p><div

style="text-indent:25px">電鍍鋅鎳合金配位劑含量：配位劑主要為有機(jī)胺，當(dāng)鍍液中配位劑不足時，鍍液中的鎳離子易產(chǎn)生沉淀而無法與鋅離子共沉積，導(dǎo)致走位不佳。配位劑能與鎳離子形成帶正電荷的[NiC8H23N3]2+，由于鋅鎳合金的電沉積是在負(fù)電荷的陰極表面進(jìn)行，鎳的配離子受到雙電層電荷的吸引作用而容易到達(dá)陰極表面放電，所以鍍層中鎳含量隨配位劑濃度增大而增加。當(dāng)鍍液中配位劑含量不足時，鍍層中的鎳含量達(dá)不到10%以上。鍍液中的配位劑體積分?jǐn)?shù)若達(dá)到80~100mL/L，則足以與全部鎳離子形成配合物，隨后配位劑濃度再繼續(xù)增加，鍍層中含鎳量也會再增加。附著于零件表面的油、銹、氧化皮等污物，就是妨礙電鍍鋅鎳合金電鍍液與金屬基體充分接觸的中間障礙物。蘇州鎳鋅</p><p
