The Preparation of Plasma-spraying Hydroxyapatite-coated Prosthesis |
|
| Abstract: | Objective:To preparate the plasma spragmg HA coated prostheris.Methods:Hip prosthesis were fully sprayed by HA coating with plasma spraying technology and outside deliver powder instrument.The coating were analyzed by X ray diffractometer,X ray energy spectrum coating analysis (ESCA),infrared rays spectroscope,SEM.The bond strength of the coating were measured.Results:The coating is mainly consist of HA,no hot dissolution on basic.The average bond strength of the coating is 29 71 MPa.Conclusion:The result of this study demonstrates that the domestic plasmaspraying HA coating keeps the character of HA.The bone strength of the coating could fix the prosthesis effectively. |
