| Summary: | 碩士 === 國立高雄應用科技大學 === 模具工程系 === 104 === In this study, color anodizing of pure titanium was performed in phosphoric acid solution within 30 s in different voltages (10-100 V) in a constant current density (10 A/cm2). The effects of anodizing parameters (voltage and concentration of electrolyte) on the anodizing film properties (color, corrosion resistance, wear resistance, and adhesion) were investigated. The color of anodized surface changed with applied voltage in order of brown (10V), dark purple (20V), blue (30V), ice blue (40V), blue green (50V), green yellow (60V), orange (70V), purple yellow (80V), light brown (90V) and red yellow (90V). The anodized titanium exhibited good corrosion resistance evaluated by salt spray test within 48h. In addition, the anodized film can adhere well on titanium surface after cross-cut tape tests
