钛(Ti)及其合金由于其良好的生物力学性能和生物化学性能,已经成为高负荷骨骼较好的替代材料。可是钛合金与骨组织弹性模量不匹配,容易造成应力屏蔽。而羟基磷灰石(HA)是自然骨无机质的主要成分,具有良好的生物活性和生物相容性,但是却因强度低、脆性大,不能用在承载部位而限制了应用。在Ti/HA复合材料的制备方法和基本性能研究现状基础上,从纳米相增强和稀土掺杂等方面综述了Ti/HA复合材料的发展现状。 Due to its good biomechanical and biochemical properties, titanium (Ti) and its alloys have become a good substitute for high-load bones. However, titanium and bone tissue elastic modulus does not match, easy to cause stress shielding. Hydroxyapatite (HA) is a major component of natural bone inorganic matter. It has good bioactivity and biocompatibility, but its application is limited due to its low strength and brittleness. Based on the research status of Ti / HA composites and their basic properties, the development of Ti / HA composites was reviewed from the aspects of nanophase strengthening and rare earth doping.
