摘要
This invention provides color development methods of metallic titanium used for manufacture of black titanium or titanium tinted in other chromatic colors. In one method, metallic titanium is treated with an alkali solution. It enables colored titanium rich in color variation with high efficiency, irrespective of the material configuration. The brightness of black is further reduced by conducting a nitriding process, after this process. In another method, the metallic titanium is oxidized after forming the titanium nitride film on its surface by nitriding it. Black titanium is produced with low brightness. In this way, colored titanium with various tones is produced. Moreover, the close adherence of the film with colors developed thereon is enhanced.
