Document Type and Number:
WIPO Patent Application WO/2022/138837
Kind Code:
A1
Abstract:
This titanium material is such that, on at least one surface, the root-mean-square inclination RΔq (rad.) satisfies the following relationship (1) if the average length RSm of a roughness curve element is greater than 8 μm and equal to or less than 300 μm, and the root-mean-square inclination RΔq (rad.) satisfies the following relationship (2) if the average length RSm of the roughness curve element is greater than 300 μm. Relationship (1): RΔq≥0.060
Relationship (2): RΔq≥2×RSm/10,000
