Effect of the wave form of the power source on anodic oxidation (electrolytic coloring) of titanium using bath containing phcsphoric acid and sulfuric acid with aluminum sulfate, cobalt (10 sulfate, ferric sulfate, chromium (III) sulfate or nickel (Ii) sulfate was studied. As the wave forms of the power source, a complete flat wave and uncomplete rectified waves, such as single-phase half-wave, two-phase half-wave, three-phase half-wave and six-phase hlaf-wave, were used. As a result, the

In addition, increasing rate of the voltage with using the uncomplete rectified wave forms was faster than that with using the complete flat wave form.
