Method of surface treating metal and metal surface treated thereby |
摘要 |
It is an object of the present invention to provide a method of metal surface treatment and a surface treated metal thereby, which has excellent corrosion resistance and can form a coat having high corrosion resistance on metal substrates such as iron, zinc, aluminum and magnesium. A method of metal surface treatment comprising the step of forming a chemical conversion coat on the surface of a metal article to be treated by a chemical conversion treatment reaction by a chemical conversion treatment agent containing a zirconium-containing compound and a fluorine-containing compound, wherein said chemical conversion treatment reaction is conducted through cathodic electrolysis treatment.
