摘　　要：采用电化学沉积法在医用金属钛表面制备钙磷盐涂层,通过XRD、FT-IR和SEM表征,侧重探索电化学沉积技术在温和条件下制备结晶结构优良的纯羟基磷灰石涂层的可控性。通过控制电流密度和反应时间,即研究在恒电量条件下羟基磷灰石涂层的电化学沉积规律性,并获得电化学沉积制备纳米有序结构羟基磷灰石涂层的最佳实验条件,同时对纳米有序结构羟基磷灰石涂层的电化学沉积机理进行讨论。The Ca/P coatings was moderately prepared by electrochemical deposition on Ti substrate in a special experiment condition in constant electric quantity. The prepared coatings was then characterized by XRD, FT-IR and SEM to correlate their chemical composition, structure and morphology with the preparation parameters. The results indicated that the electrochemically prepared Ga/P coating was pure hydroxyapatite with a fine crystallization. The formation rules of the hydroxyapatitie coatings were elucidated in the different experimental conditions. It was demonstrated that it is possible to realize a controllable preparation of nano hydroxyapatitie coatings on Ti substrate by adjusting supplied current and deposition time in the experimental conditions.
