    Abstract: PROBLEM TO BE SOLVED: To form a uniform and protective film which does not contain such a substance as to form detectable harmful hexavalent chromium, and has both adequate appearance and adequate corrosion resistance, on the surface of zinc or a zinc alloy, and to satisfy the corrosion resistance, design characteristics and a cost performance, which are bottlenecks for a replaceable technology such as a conventional trivalent-chromium-based rust preventive film to be commercialized.
    SOLUTION: This treatment agent has a liquid composition comprising: (A) a trivalent chromium ion; (B) one or more anions selected from the group consisting of a chlorine ion, a fluorine ion, a sulfate ion and a nitrate ion; (C) one or more elements selected from the group consisting of Ni, Pd, Pt, Sc, Y, V, Nb, Ta, Cu, Ag and Au; and (D) one or more compounds selected from the group consisting of Si, Al, a compound thereof and an organic acid. The rust preventive film is formed by using the liquid composition.

    Abstract: PROBLEM TO BE SOLVED: To provide a treatment liquid which stably forms a uniform film having both satisfactory black appearance and corrosion resistance without using harmful hexavalent chromium when a protective film is formed on the surface of metal, in particular, on the surface of zinc or a zinc alloy, and to provide a method therefor.
    SOLUTION: The hexavalent chromium-free black film treatment liquid contains: tervalent chromium; one or more kinds selected from an anionic group composed of sulfate ions, chlorine ions and nitrate ions; and a sulfuric compound. In the method of forming a hexavalent chromium-free black film, a substrate is brought into contact with the treatment liquid once or more times.
