【摘要】：镁及其合金具有可降解的特点,同时具有良好的生物相容性。与其他医用金属材料相比,其力学性能和弹性模量最为接近于人体骨的,被认为是近十年新一代最有潜力的生物医用植入材料之一。但是镁合金的耐腐蚀性较差,在很大程度上限制了其在医学领域的应用与发展。在镁合金表面涂覆羟基磷灰石生物陶瓷涂层,不仅能够提高镁合金的耐腐蚀性,更能够赋予其优良的生物活性。介绍了镁合金和羟基磷灰石的性能特点,综述了在镁合金表面制备羟基磷灰石涂层的工艺方法,并对镁基羟基磷灰石生物陶瓷涂层作为生物医用材料的未来发展方向进行了展望。
[Abstract]:Magnesium and its alloys are biodegradable and have good biocompatibility. Compared with other medical metal materials, their mechanical properties and modulus of elasticity are closest to those of human bone. Magnesium alloys are considered to be one of the most promising biomedical implants of the last decade, but magnesium alloys have poor corrosion resistance. To a great extent, the application and development of hydroxyapatite bioceramic coating on the surface of magnesium alloy can not only improve the corrosion resistance of magnesium alloy, but also limit its application and development in medical field. The properties of magnesium alloy and hydroxyapatite are introduced, and the process of preparing hydroxyapatite coating on magnesium alloy surface is reviewed. The future development of magnesium-based hydroxyapatite bioceramic coating as biomedical material is also prospected.
