当前在骨骼和牙齿修复治疗中作为植入物材料广泛采用了不锈钢、ＣｏＣｒ合金和钛基合金,因为它们具有很好的力学性能和耐蚀性,但其生体相容性却不很好,是其在生物医学应用中的严重缺点。因此,在改进金属植入物的生体相容性方面,一直在进行着广泛的研究。在金属表面加以羟?.. Currently, stainless steels, CoCr alloys and titanium-based alloys are widely used as implant materials in bone and dental restorations because of their good mechanical properties and corrosion resistance, but their biocompatibility is not good enough to be Its serious drawback in biomedical applications. Therefore, extensive research has been conducted in improving the biocompatibility of metal implants. In the metal surface to be hydroxy?
