摘要： Disclosed are a method and an apparatus for forming an oxide coating film with excellent corrosion resistance and adhesiveness on a cathode made of a metal plate by a simple process at low cost. A direct current voltage is applied between an anode (12) and a cathode (13) in an electrolyte solution which cathode (13) is made of a metal plate to be coated with oxide and arranged opposite to the anode (12), while supplying oxygen or a gas containing oxygen into the electrolyte solution, so that the metal plate cathode (13) is coated with oxide, thereby being formed into a oxide-coated metal plate.

摘要： A surface-treated metal material having, formed on the surface of a metal base member, an inorganic surface-treating layer that contains inorganic components or, further, having an organic surface-treating layer formed on the inorganic surface-treating layer, the inorganic surface-treating layer containing at least M (M is at least one of Ti, Zr or Al), O and F. The organic surface-treating layer comprises a silane coupling agent containing Si in an amount of 0.8 to 30 mg/m2 or a phenol-type water-soluble organic compound. The surface treatment without using chromium can be applied to various metal base members featuring excellent environmental friendliness, excellent resistance against discoloration even when applied to tin-plated steel plates, and offering excellent characteristics such as the close adhesion to the organic resin coating, adhesive property, corrosion resistance and dent resistance. Owing to the cathodic treatment in an aqueous solution, further, the surface-treated metal material can be produced at a high speed, easily and at a low cost.
