Abstract:
Objective: To study the influences of electrolytic voltages on chromatics of anodized titanium. Methods:Titanium specimens were anodized in 0.5 mol/L sulfuric acid and 0.2 mol/L phosphate acid electrolyte using different voltages. The colors of anodized titanium were measured with a computer controlled spectrophotometer, and then evaluated in the CIE1976L*a*b* uniform color scale and Mussell notation. Result: One given volt created one distinguished color. The chromatic values expressed in L*a*b* were fluctuated in different voltage conditions. The hues in Mussell notation were distributed widely within R,Y,G,P of 5 basic colors and YR,GY,BG,PB of 5 interspace colors in the range of 5 to 80 volts. Anodizing with 10 or 45 volts, the specimen's colors appeared two kinds of brilliant goldish yellow, the former reddish slightly and latter greenish a little. The spectrums of the two colors were in the range of wavelengths of yellow to red. Conclusion: The color of the anodized titanium is dependent upon the volts applied. The goldish yellow may be used to improve the esthetics of titanium dentures.
