Sažetak

The present study is focused on analyzing the change of colors of anodized titanium and effects of applied electrolytic voltages on chromatics. The titanium specimens were anodize in 20 g/L citric acid and 20 g/L baking soda electrolyte by use of different voltages. The colors of anodize titanium were measured with a spectrophotometer and then evaluated in the CIELAB color space. It is found that different volt produces different colors. Anodizing in the range of 15 V to 150 V produces respectively a wide spectrum of color ranging from brown to fuchsia. It can be concluded that the colors of the anodize titanium are dependent upon the applied voltages.
