Titanium anodizing or titanium oxide coating process has emerged globally nowadays owing to the properties of corrosion resistance, nontoxic & nonreactive nature, improve aesthetically, enhanced fatigue strength, increased osseointegration, exhibits natural biocompatibility, helps in part identification, reduced wear & tear, etc. Titanium anodizing is popular for various applications including aerospace, medical implants, automotive, sports equipment, dental, jewelry, etc. In the present investigation, 08 cylindrical samples of PureTitanium, Grade-4 material (7 for color anodizing and 1 for Type II gray color anodizing) were prepared. After that, samples were thoroughly processed & anodized by using distinct voltage as well as by using an optimum combination of parameters. The constant voltage was used during the anodizing process to achieve a consistent uniform layer thickness. Thereafter, coating thickness was measured on lowest and highest voltage samples, to know the variation of oxide layer formation. Chemical analysis was also performed to know the changes in elemental composition before and after anodizing, whether it comply the standard or not. Finally, all the samples were analyzed for fingerprint issues in case of biomedical applications.
