发明名称 Composition for metal surface treatment, metal surface treatment method and metal material
摘要 An easily handleable composition for metal surface treatment is provided which achieves foundation surface concealment, coating adhesion and corrosion resistance equal to or higher than those obtained by the conventional metal surface treatment compositions. This composition for metal surface treatment places no burden on the environment. A method for treating the surface of a metal material in which such a composition for metal surface treatment is used, and a metal material treated by such a metal surface treatment method, are also provided. Specifically disclosed is a metal surface treatment composition used for a treatment of a metal surface, which composition contains a zirconium compound and/or titanium compound substantially not containing fluorine, and an inorganic acid and/or a salt thereof. This metal surface treatment composition has a pH of not less than 1.5 but not more than 6.5.
