摘　　要：通过高温熔烧法在工业纯钛TA3表面制备出不同羟基磷灰石含量的羟基磷灰石与生物玻璃的复合涂层 (简称HA/BG) .对复合涂层的微观组织结构进行了研究 .结果表明 ,所制生物玻璃在高温处理的过程中会析出六方柱状的HA晶体 ;复合涂层具有粗糙表面 ,存在很多开放性气孔 .随着HA原始含量的增加 ,复合涂层的致密度明显降低 ,而复合涂层中HA相的衍射峰强度变化不大 .Presents HA/BG biocomposite coatings with different HA content on pure titanium(TA3) fabricated by melting at high temperature and investigation of their microstructure and points out HA precipitates in hexastyle shape precipitated from the BG fabricated in house, and the coatings were characterized by coarse surface and large quantity of open pores, and the densities of the coatings decrease with the increase of original HA content while the spectrum intensities of HA change little.
