Title:
SURFACE-TREATED METALLIC MATERIAL AND METHOD OF TREATING METAL SURFACE
Document Type and Number:
WIPO Patent Application WO/2010/082415
Kind Code:
A1
Abstract:
A surface-treated metallic material having excellent corrosion resistance and excellent suitability for coating by electrodeposition, and a method of metal surface treatment for producing the material. The surface-treated metallic material, which is obtained by treating a surface of a metallic material, comprises the metallic material and, formed on the surface, a surface treatment coating film comprising an amorphous coating film and semiconductor particles having a maximum average particle diameter of 5-300 nm, wherein the surface treatment coating film has a proportion of surface coverage by the semiconductor particles of 10-90%, the semiconductor particles are exposed on the surface of the surface treatment coating film, and the semiconductor particles are present at a density of 5-10,000 particles/µm2.
