阳极氧(yang)化技术作(zuo)为电(dian)(dian)(dian)(dian)镀(du)(du)(du)(du)行(xing)业(ye)(ye)表(biao)面(mian)(mian)处(chu)理中(zhong)常(chang)见且主要的(de)(de)技术，在电(dian)(dian)(dian)(dian)镀(du)(du)(du)(du)行(xing)业(ye)(ye)中(zhong)应用(yong)广(guang)泛(fan)。通常(chang)，金(jin)属构(gou)(gou)件(jian)(jian)(jian)如铝件(jian)(jian)(jian)等，为了具有更(geng)好的(de)(de)表(biao)面(mian)(mian)特性及光(guang)泽度，大部(bu)分都(dou)需经过阳极(ji)(ji)氧化处(chu)理工序，在其表(biao)面(mian)(mian)覆(fu)(fu)盖(gai)一层致密(mi)且具有一定光(guang)泽度的(de)(de)金(jin)属氧化物薄膜，如镍膜等。在阳极(ji)(ji)氧化过程中(zhong)，通常(chang)将待镀(du)(du)(du)(du)的(de)(de)金(jin)属如镍等作(zuo)为阳极(ji)(ji)，而将被(bei)镀(du)(du)(du)(du)的(de)(de)金(jin)属构(gou)(gou)件(jian)(jian)(jian)如铝件(jian)(jian)(jian)等作(zuo)为阴极(ji)(ji)，利用(yong)电(dian)(dian)(dian)(dian)化学法使(shi)处(chu)于(yu)阳极(ji)(ji)的(de)(de)待镀(du)(du)(du)(du)金(jin)属失(shi)去电(dian)(dian)(dian)(dian)子成为镍离子后，在电(dian)(dian)(dian)(dian)场作(zuo)用(yong)下覆(fu)(fu)盖(gai)到被(bei)镀(du)(du)(du)(du)的(de)(de)金(jin)属构(gou)(gou)件(jian)(jian)(jian)上，从而完(wan)成对被(bei)镀(du)(du)(du)(du)金(jin)属构(gou)(gou)件(jian)(jian)(jian)的(de)(de)电(dian)(dian)(dian)(dian)镀(du)(du)(du)(du)过程。
