style="text-indent:25px">化學鍍鎳是不用外來電流，借氧化還原作用在金屬制件的表面上沉積一層鎳的方法。用于提高抗蝕性和耐磨性，增加光澤和美觀。適合于管狀或外形復雜的小零件的光亮鍍鎳，不必再經(jīng)拋光。一般將被鍍制件浸入以硫酸鎳、次磷酸二氫鈉、乙酸鈉和硼酸所配成的混合溶液內(nèi)，在一定酸度和溫度下發(fā)生變化，溶液中的鎳離子被次磷酸二氫鈉還原為原子而沉積于制件表面上，形成細致光亮的鎳鍍層。鋼鐵制件可直接鍍鎳。錫、銅和銅合金制件要先用鋁片接觸于其表面上1-3分鐘，以加速化學鍍鎳。</p><p style="text-indent:25px">化學鍍鎳技術(shù)在微電子器件制造業(yè)中應(yīng)用的增長十分迅速。超大規(guī)模集成電路多層芯片的互連和導通孔的充填整平化工藝中，采用了選擇性的鎳磷合金化學鍍技術(shù)；其產(chǎn)品均通過了抗剪切強度、抗拉強度、高低溫循環(huán)和各項電性能的試驗。實踐說明，化學鍍鎳技術(shù)的應(yīng)用提高了微電子器件制造工藝的技術(shù)經(jīng)濟性和產(chǎn)品的可靠性。鑄造用模型和芯盒通常為鑄鐵或鑄鋁件，在使用過程中遭受磨料磨損，報廢很快。采用化學鍍鎳鎳表面保護之后，鑄造模型和型芯盒的質(zhì)量上等級，使用壽命明顯提高?；瘜W鍍鎳在90℃的酸性溶液或接近常溫的中性溶液、堿性溶液中進行作業(yè)?；瘜W鍍鎳技術(shù)處理后的合金層與金屬基件結(jié)合強度增大。</p><div

style="text-indent:25px">化學鍍鎳的廢液處理：次磷亞磷。鍍鎳廢液中含有大量的次磷酸鹽和其被氧化的產(chǎn)物亞磷酸鹽，由于次磷酸鈣的溶解度較大，采用CaO沉淀法不能有效的除去次磷酸鹽，但在除去鎳離子時加入的CaO會使廢液的pH值增加，此時若提高廢液的溫度，溶液中的次磷酸根可將鎳離子及其他重金屬離子還原，次磷酸根被氧化成亞磷酸根。若廢液中含有較多的次磷酸根，可添加適當?shù)难趸瘎ㄈ绺咤i酸鉀，雙氧水等）除去。當廢液的pH值在7左右時，亞磷酸鈣的溶解度將急劇下降，試驗表明，在pH值為5．5～7時，鍍液中亞磷酸鹽的除去率在95%以上。紹興快速化學鍍鎳工藝</p></p><br
