Study on high-efficient wax removing agent used for iron and steel articles;

After experimental study of static power spraying on steel pieces, it is proven that the coating of static powder spraying is even, no sag formed, and continuous even coating can bee formed at the sharp edges and rough surfaces.

This article centers on the key links in the process of the surface-priming,rate-production,corrosion and protection in packing and preservation of the steel-member,and discusses the application prospect of some new typical corrosion control technology in industrial production theoretically and practjcally.

A novel technology of acidic electroless copper plating on steel matrix was studied in this paper.

Zinc-nickel alloy electrodeposited coating shows outstanding corrosion resistance and excellent resistance to hydrogen embrittlement,which makes it a good protective coating for steel fasteners.
