摘 要:钛基合金由于具有优异的机械性能、耐腐蚀性和生物相容性等优点,是硬组织替代的优选材料.然而,在临床应用中钛基合金常常由于硬度不够、耐磨性较差而产生磨屑致使炎症发生,此外,作为一种生物惰性材料,其往往不能与骨组织形成有效的化学键合,而导致形成较差的骨整合效果.基于此,可以在钛及其合金表面离子注入磷元素,改善钛基合金的性质并扩展其临床应用.综述了磷离子注入钛基合金表面生物医用改性的研究进展,对该方法改善钛基金属生物学性质及其在临床上广泛医用的前景做了展望.Titanium-based alloys are preferred materials for hard tissue substitution due to their excellent mechanical properties, corrosion resistance and biocompatibility. However, in clinical application, titanium-based alloys often produce debris due to their insufficient hardness and poor wear resistance, which leads to inflammation. In addition, as a kind of biological inert material, it often fails to form effective chemical bonds with bone tissue, resulting in poor osseointegration effect. Based on this, phosphorus can be implanted on the surface of titanium and its alloys to improve the properties of titanium-based alloys and expand its clinical application. In this paper, the research progress of biomedical modification of titanium-based alloys by phosphorus ion implantation is reviewed. The prospects of this method for improving the biological properties of titanium-based alloys and its extensive clinical application are prospected.
