| 摘 要： | 羟基磷灰石由于其良好的生物活性,被广泛的用作医用植入体的表面涂层材料.采用微束等离子喷涂(Microplasma Spraying,MPS)I艺在Ti-6Al-4V基体上制备羟基磷灰石涂层,通过扫描电镜(SEM)、X射线衍射(XRD)和傅里叶红外光谱(FTIR)分析了热处理对涂层相组成和表面形貌的影响规律.研究表明:微束等离子喷涂制备的羟基磷灰石涂层在经过热处理后结晶度提高,并且非晶相和杂质相转化成为HA结晶相.同时,羟基和磷酸根的完整性得到了恢复.过高的热处理温度易引起涂层裂纹等缺陷的增加,也容易造成羟基脱离造成HA分解.合理的热处理温度范围为600～700℃,保温时间为3 h.

| Abstract: | Hydroxyapatite (HA) is widely used as surface coatings on biomedical metallic implants because of its good bioactivity. HA coatings were deposited onto Ti-6A-l4V substrate by microplasma spraying (MPS) in this research. The effect of heat treatment on the phase and surface morphology of HA coatings is discussed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and fourier-transform infrared (FTIR) analysis. The results from the present investigation suggest that the crystallinity of MPS coatin... |
