摘要
采用溶胶-凝胶工艺在经过微弧氧化预处理的钛基体表面制备HA/TiO2生物复合涂层,观察了涂层的表面及截面微观形貌,测定涂层的表面成分和涂基结合力,并且进行了体外溶解性实验。结果表明:涂层表面涂覆均匀,无明显裂纹;涂层截面层次清晰,涂基结合力较高,可以达到40N左右;涂层在模拟体液中有较好抗体液溶解性和生物相容性,可以提高材料的植入寿命,是一种理想的生物涂层材料。
HA/TiO2 bio-composite coating is prepared by sol-gel method on the surface of titanium （Ti） substrate pre-treated via micro -arc oxidation. The coating surface and its sectional micro-morphologies are observed. The surface components of coating and the combined strength between coating and substrate are determined. Also, the in vitro dissolution characters are tested. The results indicate that： the coating surface is symmetrical without apparent cracks; the coating section surface layers are clear, the combined strength between coating and substrate is high, reach as high as 40N or so; and the coating in simulated body fluid is of better anti-body fluid solubility and bio-compatibility so that the implanted service life of material can be imorove.
