PURPOSE: A method for preparing a bio material using coating of hydroxyapatite/zirconia composites and a bio material prepared by the same are provided to effectively form a hydroxyapatite/zirconia composite ceramic coating layer even in a short processing time and a low processing temperature by employing micro-arc oxidation. CONSTITUTION: A method for preparing a bio material using coating of hydroxyapatite/zirconia composites comprises steps of: forming electrolyte in an electrolytic cell from a mixed solution of KH_2PO_4, CaCl_2, and ZrCl_4, immersing a titanium anode and a metal cathode with a higher reduction potential than titanium in the electrolytic cell, applying electric current and voltage to the anode and cathode to generate arc discharge that creates plasma, and forming a hydroxyapatite/zirconia composite layer on the titanium surface from ion materials in the electrolytic cell by using the plasma. |
