Document Type and Number:
Japanese Patent JP5171865
Kind Code:
B2
Abstract:
It is an object of the invention to provide a method for production of various oxide and/or hydroxide coatings with various functions and constructions on metal materials from aqueous solutions, and metal materials having such coatings. There are provided specifically a method for production of a metal oxide and/or metal hydroxide coated metal material characterized by immersing a metal material or electrolyzing a conductive material in an aqueous treatment solution at pH 2-7 containing metal ion and fluorine ion in a 4-fold molar ratio with respect to the metal ion, and/or containing a complex ion comprising at least a metal and fluorine in a 4-fold molar ratio with respect to the metal, to form on the surface of the metal material a metal oxide and/or metal hydroxide coating containing the metal ion, as well as a metal oxide and/or metal hydroxide coated metal material characterized by having a metal oxide and/or metal hydroxide coating produced by the method.
