style="text-indent:25px">電鍍鋅的鍍鋅液由含有鍍覆金屬的化合物、導(dǎo)電的鹽類、緩沖劑、pH調(diào)節(jié)劑和添加劑等的水溶液組成。通電后，鍍鋅液中的金屬離子，在電位差的作用下移動(dòng)到陰極上形成鍍層。陽極的金屬形成金屬離子進(jìn)入鍍鋅液，以保持被鍍覆的金屬離子的濃度。在有些情況下，如鍍鉻，是采用鉛、鉛銻合金制成的不溶性陽極，它只起傳遞電子、導(dǎo)通電流的作用。電解液中的鉻離子濃度，需依靠定期地向鍍液中加入鉻化合物來維持。鍍鋅時(shí)，陽極材料的質(zhì)量、鍍鋅液的成分、溫度、電流密度、通電時(shí)間、攪拌強(qiáng)度、析出的雜質(zhì)、電源波形等都會(huì)影響鍍層的質(zhì)量，需要適時(shí)進(jìn)行控制。常州液壓閥塊鍍鋅鎳合金專業(yè)生產(chǎn)電鍍鋅鎳合金的不同功能應(yīng)用領(lǐng)域廣闊。</p><div

電鍍鋅鎳合金加工技術(shù)已經(jīng)應(yīng)用到各行各業(yè)。通過把除銹后的金屬浸泡在500℃的鋅液里，使金屬表面粘覆著一層鋅膜，形成了抗腐的功效，技巧十分容易掌握。目前國內(nèi)提高熱鍍鋅防腐的手法通常有：增加鍍鋅層的厚度、改善鋅液成分、采用合金方式增加防腐強(qiáng)度、兩次熱度法。其中采用合金化方法是使用鋅鐵合金熱鍍，這種方式鍍層的抗腐蝕性比純鋅鍍層高很多。再者，改善鋅液成分非常有助于鋅液的黏合強(qiáng)度和抗腐蝕性，比如：Ｚｎ-6%Ａｌ-3%Ｍｇ合金熱鍍層或者55% Ａｌ-43.5%Ｚｎ-1.5%Ｓｉ合金熱鍍層等等。另外，二次熱鍍法是指采用鍍鋅和鍍合金兩步，要先給次先鍍純鋅，待冷卻后再鍍合金。這種方法較早起源在歐洲，大量應(yīng)用在汽車、家電等領(lǐng)域。鋅鐵合金鍍層性能鍍層性能即鍍層質(zhì)量，反應(yīng)在鍍層外觀與鍍層結(jié)構(gòu)的防護(hù)性上。鋅鐵合金鍍層的結(jié)晶比單金屬鋅鍍層細(xì)致、光亮，色澤均勻，其光亮度優(yōu)于鋅鍍層，鍍層手感也比純鋅層細(xì)膩，鍍層與基體的結(jié)合力良好。</p><p
