摘要
目前钛及钛合金在国民经济和国防工业上的应用越来越广泛,为了提高和改善其使用特性,需要对其进行表面处理。金属表面电沉积是最常用且比较有效的方法,通过金属表面电沉积就可以提高和改善其功能性、装饰性、耐蚀性以及与涂覆层的结合强度。金属电沉积的关键是预处理问题,而预处理的关键是在其表面形成适宜的"活性膜"。电沉积层的性质取决于电解液的组成以及温度、pH值、电流密度、电沉积时间等因素。
Titanium and titanium alloys are used more and more widely in national economics and defense industry currently. To improve the application characteristics, some surface treatments are adopted. Electrodeposition of metal is a common and convenient method. By electrodeposition of metal, the functionality, decorate properties, anticorrosion and the bonding force with top layer can be enhanced. Pretreatment plays an important role in electrodeposition, and forming proper ＂active film＂ is the key process for pretreatment. The performance of electrodeposition deposit layer depends on some parameters, such as the electrolyte compositions, temperature, pH value, current density, deposit time and so on.
