style="text-indent:25px">汽車零件鋅鎳合金電鍍工藝添加劑：1.氫氧化鈉。氫氧化鈉主要起絡(luò)合作用,過量的氫氧化鈉是穩(wěn)定電鍍液的必要條件。氫氧化鈉為強(qiáng)電解質(zhì),有利于降低鍍液內(nèi)阻,減少電能的消耗和防止鍍液溫升過快,同時(shí)有利于陽極溶解。若氫氧化鈉含量過高,則會(huì)引起陽極溶解過快,使鍍液中鋅含量自然升高,溶液比例失調(diào),造成故障。2.絡(luò)合劑。眾所周知,鎳離子在一般的堿性溶液中形成氫氧化鎳沉淀,無法參與電鍍反應(yīng),絡(luò)合劑的加入使溶液穩(wěn)定。絡(luò)合劑BASE是多元胺化合物,也是環(huán)氧氯丙烷系列的多聚型表面活性物。其分子中含有—OH、—N、—CH等多個(gè)極性基團(tuán),致使能定向地在陰極表面上產(chǎn)生特殊的吸附。它又是一種季胺鹽,帶正電荷,使吸附變得容易進(jìn)行,絡(luò)合劑BASE不*可以使兩種金屬的電極電位接近,而且還可以使電流密度范圍加寬,對(duì)雜質(zhì)敏感性降低,鍍層塑性增加、鍍層結(jié)晶細(xì)致,分散能力和深鍍能力提高。添加劑過量,將會(huì)造成鍍層脆性增大;添加劑含量過低,則會(huì)降低鍍液的電流效率。啟東高鹽霧試驗(yàn)的鋅鎳電鍍鋅鎳合金是一種有效的金屬防腐方式。</p><div

style="text-indent:25px">電鍍鋅-鎳合金一般使用分開的單金屬陽極板，并裝上陽極袋。但由于鋅和鎳兩種金屬的溶解電位相差較大，還要兩個(gè)分開的陽極電流。如采用一臺(tái)整流電源，即在鋅陽極電路。如采用一臺(tái)整流電源，即在鋅陽極和鎳陽極的電路中分別串入一個(gè)可變電阻，來控制兩種金屬陽極各自溶解的電位和電流密度。其兩陽極比例應(yīng)根據(jù)合金組成而確定，如含鎳量為13%左右，分開的鋅鎳陽極面積比一般為9:1。如果合金組成中鎳含量較低，則只掛鋅陽極，而低含量的鎳可采取在鍍液中適當(dāng)增加該金屬鹽類的方法，來得到一定的合金鍍層。如果采用硫酸鹽電鍍鋅鎳合金的鍍液，其陽極可全部使用不溶性陽極。</p><p style="text-indent:25px">電鍍鋅鎳合金工藝要注意什么？1.要注意的就是基材的前處理，電鍍基材表面的結(jié)合力、導(dǎo)電性能，平整度，是否有殘留物，這些都是要考慮的。2.要注意的就是添加劑的問題，電鍍槽內(nèi)的各類添加劑一定要及時(shí)補(bǔ)充，否則會(huì)導(dǎo)致電鍍的失敗或其他問題，所以，這也就需要在操作時(shí)記錄好各個(gè)流程步驟的情況，及時(shí)進(jìn)行補(bǔ)充添加。3.對(duì)于電鍍鋅鎳合金時(shí)電流大小以及時(shí)長的把控，鍍鋅鎳合金鍍層的速度和厚度就是由這兩個(gè)因素決定的，但是液并不是越大越好，比如如果電流過大，就會(huì)導(dǎo)致鍍層變色，得不償失。至于厚度也是需要根據(jù)需求來設(shè)定電鍍的時(shí)長。這些就需要經(jīng)過多次的驗(yàn)證對(duì)比，然后找到可以又快又好的電鍍鋅鎳合金的參數(shù)進(jìn)行設(shè)置關(guān)于電鍍鋅鎳合金的要點(diǎn)注意一下就好，電鍍鋅鎳合金的原理其實(shí)很簡(jiǎn)單，無論是傳統(tǒng)**物鍍銀還是現(xiàn)在新出的無氰電鍍銀，基本流程都是差不多的。鑄鐵件酸性電鍍鋅鎳合金工藝鍍前處理：酸洗，酸洗是保證鍍層結(jié)合力良好的關(guān)鍵。</p><div
