style="text-indent:25px">電鍍鋅鎳合金是一種電化學(xué)過(guò)程，也是一種氧化還原過(guò)程。電鍍的基本過(guò)程是將零件浸在金屬鹽的溶液中作為陰極，金屬板作為陽(yáng)極，接直流電源后，在零件上沉積出所需的鍍層。例如：鍍鎳時(shí)，陰極為待鍍零件，陽(yáng)極為純鎳板。不是所有的金屬離子都能從水溶液中沉積出來(lái)，如果陰極上氫離子還原為氫的副反應(yīng)占主要地位，則金屬離子難以在陰極上析出。根據(jù)實(shí)驗(yàn)，金屬離子自水溶液中電沉積的可能性，可從元素周期表中得到一定的規(guī)律。陽(yáng)極分為可溶性陽(yáng)極和不溶性陽(yáng)極，大多數(shù)陽(yáng)極為與鍍層相對(duì)應(yīng)的可溶性陽(yáng)極，如：鍍鋅為鋅陽(yáng)極，鍍銀為銀陽(yáng)極，鍍錫-鉛合金使用錫-鉛合金陽(yáng)極。但是少數(shù)電鍍由于陽(yáng)極溶解困難，使用不溶性陽(yáng)極，如酸性鍍金使用的是多為鉑或鈦陽(yáng)極。鍍液主鹽離子靠添加配制好的標(biāo)準(zhǔn)含金溶液來(lái)補(bǔ)充。鍍鉻陽(yáng)極使用純鉛，鉛-錫合金，鉛-銻合金等不溶性陽(yáng)極。浦東新區(qū)鍍鋅鎳供應(yīng)商電鍍鋅鎳合金有較好的可焊性。</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(shí)，鍍液中的鎳離子易產(chǎn)生沉淀而無(wú)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(shí)，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(huì)再增加。</p><p
