Abstract: Al₂O₃ material was synthesized by using high purity alumina micro-powder and Mg-Zr-Y composite additives at temperature of 1600℃, which had good mechanics property of 416MPa bending strength and 5.46MPa·m^1/2 fracture toughness. Femur head prosthesis of hip joint was prepared by using this material; Ti alloy femur handle was sprayed bioactive hydroxyapatite (HA) by plasma on surface, which improves the chemistry stability and biocompatibility of Ti alloy; ceramic-metal combination artificial hip joint femur prosthesis was made by combining Al₂O₃ femur head with Ti alloy femur handle, so the manufacturing process is improved and the property and application flexibility are advanced.
