摘　　要：观察了等离子喷涂和电结晶 碱液处理羟基磷灰石涂层模拟体液中的溶解性 ,XRD和SEM分析表明 :等离子喷涂及热处理羟基磷灰石涂层在浸泡时CaO和α TCP逐渐消失 ,出现CaCO3 ,两种涂层的溶解性都较强 ;电结晶 碱液处理羟基磷灰石涂层在浸泡时成分基本不变 ,溶解性较弱。This paper has studied the dissolution behavior of the plasma sprayed and electrochemically prepared hydroxyapatite(HA) biocoatings in the simulated body fluid. XRD and SEM show that the plasma sprayed coating and post heat treated HA coatings are more soluble, and CaO and α TCP in the coatings gradually disappear and CaCO 3 forms during the immersion. The composition of the electrocrystallized and alkaline treated HA coatings is basically unchanged, and the coatings are more stable in the simulated body fluid.
