PURPOSE:To improve the bioaffinity and the balance of coating layer by forming a calcined coating layer contg. hydroxyl apatite and Ca3(PO4)2 on the surface of a ceramics sintered body. CONSTITUTION:An aq. slurry mixture contg. the hydroxyl apatite and Mg(PO3)3 at 50/1 to 50/3 weight ratios and a binder (e.g.: CMC) is applied on the surface of the ceramics sintered body and is dried; thereafter, the coating is calcined at 1,000 to 1,350 deg.C. The calcined coating layer contg. the hydroxyl apatite and the Ca3(PO4)2 at 4/1 to 1/5 weight ratios and having 10 to 300mum thickness is formed. |
