Abstract

The present invention is a method of forming a phosphate chemical treatment film which is efficient and allows a high-quality chemical film to be obtained, by which a substance to be treated is subjected to electrolytic treatment while removing the sludge, which consists of impurities other than the unavoidable impurities in the phosphate chemical treatment bath.
According to this method, an adequate phosphate chemical treatment film may be formed onto any type of metal material, to provide phosphate chemical treatment films having thicknesses not obtainable by the prior art.
