Anodic polarization of biomaterial zircaloy-4 produced interference-coloured thin oxides growth involved the passage of a current observed upto the breakdown voltage, which is varied. The growth kinetics of zirconia ceramic have been studied by Faraday 1st law by inorganic electrolytes as 0.1M potassium dihydrogen orthophosphate and 0.1M cupric sulphate at a constant current density, 8mA.cm-² at room temperature Thickness estimates were made from capacitance data. The formation rate, faradaic efficiency and differential field were found to increase at constant current density for zirconia ceramic. Investigated the Growth kinetics of different anodization voltages shown coloured zirconia formed on the surface of entire thin oxide film by the incorporation of inorganic anions from the inorganic electrolytes, such as PO3-4 and sulphate anions ( SO2-4 ) have shown better improvement. Zirconia ceramics applicable in medical sciences as implant material is recorded for exhibiting enhanced mechanical properties as well as biocompatibility in hip orthroplasty as well as bone implants. Further research needs for betterment of human kind.
