RESULTS: The surface feature of each sample showed globular granule with caky structure and air pore. The crystal structure of group A, B, C mainly showed characteristic absorption band of Ca102(PO4)6 which degraded while antimicrobial content increased. Except Ca102(PO4)6 and CaZr (PO4)2, Na6CaP2O9 also appeared in group D.

结果：4组涂层材料镜下表面形貌相似，均为球状颗粒中夹杂&饼状&结构及气孔；A、B、C组晶相主要呈现羟基磷灰石主要成分Ca102(PO4)6的特征峰，且随抗菌剂含量上升，峰值降低。D组除主要呈现Ca102(PO4)6的特征峰外，还出现CaZr(PO4)2、Na6CaP2O9等新相。
