ABSTRACT:
The present invention provides a process for coloring titanium, or its alloys which comprises the steps of anodizing titanium metal, or its alloy in an electrolytic solution until the voltage reaches a predetermined voltage at a constant current temporarily cutting off the current supply to interrupt the anodizing; and then supplying a direct current again at a predetermined current density to continue anodizing, wherein the color tone of the anodic oxide film formed on the titanium or its alloy is adjusted by controlling the supplied amount of current, without causing an increase in voltage. By the coloring process of the present invention, the color of titanium metal or its alloys can be changed to various color tones at low voltages.
