| 摘 要： | 采用亚音速火焰喷涂方法及涂层处理技术，以Ti6A14V为基体，喷涂钛-生物玻璃，涂层经700℃晶化处理．用扫描电子显微镜（SEM）观察涂层显微结构，X射线衍射法（XRD）测试涂层相组成，采用基于GIXRD的残余应力分析方法测量涂层残余应力．结果表明：亚音速火焰喷涂钛-生物玻璃涂层沿裂纹处有晶态析出物TiO2，起到弥合裂纹的作用．添加生物玻璃G后，涂层表面有针状结构晶体Na2RO。，析出，新相Na2Ti60。，具有一定的有生物活性．涂层残余应力均为压应力，其值与生物玻璃含量成正比．

| Abstract: | Ti/bioglass was sprayed on Ti6A14V substrate by subsonic flame spraying and the coatings were crystallized at 700℃. Microstructure, phase composition and residual stress of the coatings were characterized by SEM, XRD and GIXRD （ gazing incidence X - ray diffraction） respectively. Results showed that crystal TiO2, which precip- itated along the cracks of Ti/Bioglass coatings by subsonic flame spraying, played a role in healing up the cracks.Mter bioglass G was added, needle crystal Na2Ti6O13 with bioactivity precipitated on the surface of the coatings. Residual stress of the prepared Ti/Bioglass coatings was compressive stress in direct proportion with the bioglass content. |
