METHOD FOR PRODUCING TITANIUM-PLATED MEMBER

A method for manufacturing a titanium-plated member includes: preparing a substrate having an electrically conductive surface; immersing the substrate in a molten-salt titanium plating solution composition containing ions of at least one Group I metal selected from the group of Li+and Na+, F-, and Tin+; forming a titanium plating film on the surface of the substrate by applying electric current to cause the substrate immersed in the molten-salt titanium plating solution composition to serve as a cathode and cause the surface of the substrate to be coated with titanium; cleaning the titanium plating film by bringing the titanium plating film into contact with a cleaning molten salt, to remove a first adhering matter caused to adhere to a surface of the titanium plating film during the forming of the titanium plating film, the cleaning molten salt containing at least one compound selected from the group consisting of alkaline metal chloride, alkaline earth metal chloride, and potassium fluoride; and cleaning the titanium plating film with water to remove a second adhering matter caused to adhere to the surface of the titanium plating film during the cleaning with the cleaning molten salt.
