Title:
SURFACE-SMOOTHENED METAL MEMBER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/157410
Kind Code:
A1
Abstract:
Provided are a surface-smoothened metal member and a method for easily and effectively manufacturing the same, said surface-smoothened metal member having been smoothened to such an extent that in a surface of a large metal member formed from titanium or a titanium alloy, a flat surface portion has a maximum height roughness (Rz) of 1.1 µm or less and a portion with a curvature radius of 0.05 to 2.5 mm has a maximum height roughness (Rz) of less than 2 µm. This method for manufacturing the surface-smoothened metal member is characterized in that an anodic oxide film is formed on a surface of a substrate formed from titanium or a titanium alloy by applying an anodization treatment to the substrate, and the surface of the substrate is smoothened by removing the anodic oxide film.
