ABSTRACT:
An electrolytic conversion solution for metal surface treatment comprises (A) a vanadate or a vanadium salt of an inorganic acid and (B) an organic acid having a reducing ability, and has a pH of not less than 7. The electrolytic conversion solution can be employed in a method for electrolytic conversion treatment which comprises the steps of immersing a subject to be treated in the treating solution and then cathodically electrolyzing the subject in the solution. The electrolytic conversion solution is free of any chromate compound and permits the formation of uniform corrosion-resistant film on the surfaces of various kinds of metallic materials without impairing the working environment and causing any environmental pollution.
