针对锌合金压铸件表面的一些特殊要求 ,开发出了一种锌合金压铸件钝化工艺 ,经该工艺处理后 ,形成了均匀 ,有光泽 ,耐蚀性强的钝化膜。
Aiming at some special requirements of zinc alloy die-casting surface, a passivation process of zinc alloy die-casting has been developed. After the process is processed, a uniform, shiny and corrosion-resistant passivation film is formed.
