dc.description.abstractAbstractThe electrolytic deposition of zirconia coating on biomedical implant F-75 CoCrMo alloy was conducted in an aqueous solution of zirconyl nitrate 〔ZrO(NO3)2〕. By controlling different elertrochemical parameter ( concentration, potential, time ) and different sintering conditions, the better one can be determined. Through dynamic polarization tests, SEM/EDS, XRD, AES/ESCA, wear tests and scratch tests, the characterization of these ZrO2 coated specimens was investigated. Diagrams of XRD showed that the zirconia films were monoclinic phase after annealed at T1-t4 or T2-t4, tranformed to tetragonal phase after annealed at T5-t4, and the mixture of the tetragonal and monclinic phases at T7-t4. The cycle polarization test showed that the substrate with zirconia exhibited a better protection potential and a lower corrosion potential than the substrate without zirconia. For the wear test with a loading stress of 60MPa, the ZrO2 coated and uncoated specimens were wore with UHMWPE for 1500 cycles. After the wear test, no ZrO2 coated films were peeled off. It indicates that the bonding strength between ZrO2 and substrate are strong enough to prevent breaking during exercise. Also, the wore qualities of UHMWPE to the ZrO2 coated specimen is an half of that to the uncoated specimen. Obviously, the wear debris was reduced for the ZrO2 coated CoCrMo alloy. Further, it can prolong the use life of implant material.zh_TW
