摘要

PROBLEM TO BE SOLVED: To provide a surface treatment method for a titanium metal member capable of applying a beautiful and various patterns having various shapes such as line patterns, wavy patterns, striped patterns, patterns, characters and characters. do. SOLUTION: This is a surface treatment method for treating the surface of a titanium metal member made of titanium or a titanium alloy, which comprises a patterning polishing step of performing a patterning polishing process on the surface of a titanium metal molding member. It is provided with a high temperature oxidation treatment step of producing a titanium metal member by subjecting the titanium metal molding member obtained by the patterning polishing step to a high temperature oxidation treatment in an air or oxygen atmosphere.
