Abstract
In the previous paper, we proposed a new method of coloring titanium alloy by electrical discharge machining (EDM) in dielectric water. It was confirmed that coloring by EDM is caused by an interference phenomenon in the anodic oxide film generated on the EDMed surface. In order to apply this new coloring method to titanium products, it is necessary to evaluate the properties of the colored surface. In this study, the corrosion resistance, the weatherability and the wear resistance of the colored surface were discussed. As a result, it was confirmed that the surface colored due to the presence of an oxide layer has high corrosion resistance and excellent weatherability. Moreover, the wear resistance of the colored surface was improved as an additional effect of EDM.
