TITANIUM LESS SUSCEPTIBLE TO DISCOLORATION IN THE ATMOSPHERE AND METHOD FOR PRODUCING SAME |
摘要 |
<p>Titanium resistant to discoloration in an atmospheric environment characterized by having an average carbon concentration of 14 at% or less in a range to a depth of 100 nm from the surface and having an oxide film of a thickness of 12 to 40 nm at its surface. Titanium resistant to discoloration in an atmospheric environment characterized in that, in X-ray diffraction of its surface, a ratio (X1/X2) of a (200) peak intensity X1 of TiC to a (110) peak intensity X2 of titanium is not more than 0.18 and by having an oxide film of a thickness of 12 to 40 nm at its surface. <IMAGE></p> |
