介绍了钛合金表面加弧辉光离子无氢渗镀碳、双层辉光离子无氢渗碳、双层辉光离子渗铬、渗铜等 表面处理的新方法；检测结果显示在钛合金表面均形成了梯度合金层，进一步检测表明，表面渗镀合金层对 改善钛合金耐磨、耐蚀和阻燃性均有显著的作用。

Aimed at improving wear, corrosion resistance and enhancing fire retardance, several plasma surface treating methods on titanium alloys had been presented, which included add-arc glow hydrogen-free carburizing plasma depositing on titanium alloy, double glow plasma hydrogen-free carburizing on titanium alloy, double glow Mo diffusing,  double glow Cr diffusing, double glow Cu diffusing. The results showed that gradient layer had formed on the titanium alloys surface, that was of great significance on wear, corrosion resistance and fire burning resistance.
