style="text-indent:25px">化學(xué)鍍鎳的歷史與電鍍相比，比較短暫，化學(xué)鍍鎳弄清楚了形成涂層的催化特性，發(fā)現(xiàn)了沉積非粉末狀鎳的方法，使化學(xué)鍍鎳技術(shù)工業(yè)應(yīng)用有了可能性。但那時(shí)的化學(xué)鍍鎳溶液極不穩(wěn)定，因此嚴(yán)格意義上講沒有實(shí)際價(jià)值?；瘜W(xué)鍍鎳工業(yè)化生產(chǎn)起步較晚，但近幾年的發(fā)展十分迅速，不僅有大量的論文發(fā)表，還舉行了詳細(xì)性的化學(xué)鍍會(huì)議，據(jù)第五屆化學(xué)鍍年會(huì)發(fā)表文章的統(tǒng)計(jì)就已經(jīng)有300多家廠家，但這一數(shù)字在當(dāng)時(shí)應(yīng)是極為保守的。據(jù)推測(cè)我們每年的化學(xué)鍍鎳市場(chǎng)總規(guī)模應(yīng)在300億元左右，并且以每年10%～15%的速度發(fā)展?；瘜W(xué)鍍鎳層兼?zhèn)淞肆己玫哪臀g與耐磨性能。用化學(xué)鍍鎳沉積的鍍層，有一些不同于電沉積層的特性。舟山化學(xué)鍍鎳退鍍</p><p

style="text-indent:25px">用次磷酸鹽作還原劑的化學(xué)鍍鎳溶液中鍍得的鍍層含有4%～15%的磷，是一種鎳磷合金，以硼氫化物或胺基硼烷作還原劑得到的鍍層才是純鎳層，含鎳量可達(dá)99.5%以上。剛沉積出來的化學(xué)鍍鎳層是無(wú)定型的，呈非晶型薄片狀結(jié)構(gòu)物質(zhì)。鍍層中磷含量主要決定于溶液的pH值，隨著pH值降低，磷含量增大。常規(guī)的酸性化學(xué)鍍鎳溶液中沉積出的鍍層含磷量為7%～12%，而堿性溶液中沉積的鎳層含磷量為4%～7%。此外，溶液的組成及各組分的含量和它們的相對(duì)比率，以及溶液的工作溫度等都對(duì)含磷量有一定的影響。舟山化學(xué)鍍鎳退鍍</p></p><br
