摘要 综合介绍了文献及中国科学院上海硅酸盐研究所在等离子体喷涂生物涂层方面的近期研究进展。羟基磷灰石涂层已在临床上获得应用,但使用效果仍然受其较低的结合强度和结晶度所制约。通过优化喷涂工艺和制备羟基磷灰石基复合涂层,可有效提高羟基磷灰石涂层的结合强度和结晶度。此外,为了获得综合性能优良的植入体材料,制备了多种新型的生物活性陶瓷涂层。纳米氧化钛涂层经合适工艺的后处理可具有良好的生物活性,由于其与钛合金基体有较高的结合强度,在体液环境下具有高稳定性和生物相容性,使纳米氧化钛涂层成为一种具有发展前景的植入体涂层候选材料。新型生物活性硅酸钙涂层具有良好的生物活性,与骨组织能形成有效结合。此外,对这些新型涂层的生物活性机制也做了必要的描述。 The development and use of plasma sprayed bioceramic coatings are introduced by reviewing selected literatures and the experiments performed at the Shanghai Institute of Ceramics,Chinese Academy of Sciences.The plasma sprayed hydroxyapatite coating has been applied in clinical treatment,although this type of coating is still plagued with low crystallinity and poor bonding strength to titanium alloys.The bonding strength and crystallinity of plasma sprayed hydroxyapatite can be improved by optimizing the spr...
