电镀锌基合金的应用与发展

Application and Development of Electrodeposition of High Corrosion Resistant Zn Alloys

综述了电镀锌基合金(Zn-Ni、Zn-Co、Zn-Fe、Zn-Sn)的工艺特点、镀层性能及其应用,对几种合金镀层的性质进行了对比。结果表明,经钝化处理的锌基合金镀层其耐蚀性大大提高,镀层的防护性能与合金组成密切相关。

The Zn based alloys electroplating technologies are discussed, and its development trend is also reviewed. The characteristics of five Zn based alloys (Zn-Ni, Zn_Co, Zn-Fe, Zn-Ti and Zn-Sn) electrodeposits are illustrated.
