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 ametal article tobe treatedbya 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.
