style="text-indent:25px">化學(xué)鍍鎳經(jīng)過多年的不斷探索與研究，近幾年已發(fā)展極成熟了，化學(xué)鍍鎳水幾乎適用于所有金屬表面鍍鎳。如：鋼鐵鍍鎳，不銹鋼鍍鎳，鋁鍍鎳，銅鍍鎳等等，它同樣適用于非金屬表面鍍鎳。比如：陶瓷鍍鎳，玻璃鍍鎳，金剛石鍍鎳，碳片鍍鎳，塑料鍍鎳，樹脂鍍鎳等等。使用范圍是非常普遍的?；瘜W(xué)鍍鎳的歷史與電鍍相比，比較短暫，在國外其真正應(yīng)用到工業(yè)**是70年代末80年代初的事。1844年，有人發(fā)現(xiàn)金屬鎳可以從金屬鎳鹽的水溶液中被次磷酸鹽還原而沉積出來。</p><p style="text-indent:25px">化學(xué)鍍鎳可沉積在各種材料的表面上，例如：鋼鎳基合金、鋅基合金、玻璃、陶瓷、塑料、半導(dǎo)體等材料的表面上，從而為提高這些材料的性能創(chuàng)造了條件。不需要一般電鍍所需的直流電機(jī)或控制設(shè)備，熱處理溫度低，只要在400℃以下經(jīng)不同保溫時(shí)間后，可得到不同的耐蝕性和耐磨性，因此，它不存在熱處理變形的問題，特別適用于加工一些形狀復(fù)雜，表面要求耐磨和耐蝕的零部件等?；瘜W(xué)沉積層的厚度可控，其工藝簡單，操作方便，溫度低，成本比其它表面處理防護(hù)低，適用于在中、小型工廠或小批量生產(chǎn)?；瘜W(xué)鍍不*可以在金屬表面施鍍，通過特殊的活化、敏化處理，也可以在非金屬表面上進(jìn)行。</p><div

style="text-indent:25px">在電鍍鎳液中，除了一小部分氫是由NiSO4和H2PO3反應(yīng)產(chǎn)生以外，大部分氫是由于兩極通電時(shí)發(fā)生電極反應(yīng)引起的水解而產(chǎn)生，在陽極反應(yīng)中，伴隨著大量氫的產(chǎn)生，陰極上的氫與金屬Ni—P合金同時(shí)析出，形成（Ni—P）H，附著在沉積層中，由于陰極表面形成超數(shù)量的原子氫，一部分脫附生成H2，而來不及脫附的就留在鍍層內(nèi)，留在鍍層內(nèi)的一部分氫擴(kuò)散到基體金屬中，而另一部分氫在基體金屬和鍍層的缺陷處聚集形成氫氣團(tuán)，該氣團(tuán)有很高的壓力，在壓力作用下，缺陷處導(dǎo)致了裂紋，在應(yīng)力作用下，形成斷裂源，從而導(dǎo)致氫脆斷裂。氫不*滲透到基體金屬中，而且也滲透到鍍層中，據(jù)報(bào)道，電鍍鎳要在400℃×18h或230℃×48h的熱處理之后才能基本上除去鍍層中的氫，所以電鍍鎳除氫是很困難的，而化學(xué)鍍鎳不需要除氫?；瘜W(xué)鍍鎳與通常的鋼鐵、銅等基體的結(jié)合良好，結(jié)合力不低于電鍍鎳層和基體的結(jié)合力。鋁化學(xué)鍍鎳加工報(bào)價(jià)</p><p
