汽车钢圈锌钙系中温磷化处理

Moderate Temperature Zn-Ca Phosphating Technology for Automobile Wheel Rims

针对汽车钢圈,采用对比试验的方法,研究出锌钙系中温磷化液的配制方法和使用工艺。新研制的锌-钙系中温磷化液与外购磷化液相比,所形成的磷化膜在耐蚀性和膜层质量方面更加优越。试验中大部分药品直接用工业品,从而操作费用大为降低。

A moderate temperature Zn-Ca phosphating technology was developed and successfully used for automobile wheel rims.Most of the chemicals used in the process were industrial products,resulting in a great reduction of treatment cost.
