摘要
钛及钛合金作为生物医用金属材料得到广泛研究和应用,为了更好地满足钛及钛合金在人体中植入后低弹性模量、生物活性等需求,采用粉末冶金的方法通过添加羟基磷灰石制备钛基羟基磷灰石(HA)生物复合材料成为了研究的热点.本文基于钛及钛合金的基础性能和存在的问题,从热压(HP)、粉末注射成形(PIM)和放电等离子烧结技术(SPS)等粉末冶金方法制备生物复合材料以降低弹性模量、提高生物活性、改善耐腐蚀性等方面综述了钛基HA生物复合材料的研究进展,分别列举了 α型,α+β型和/3型钛合金与HA合成制备钛基HA生物复合材的代表性案例,并提出了面临的挑战以及发展方向的建议.
Abstract
Titanium and titanium alloys have been widely studied and applied as biomedical metal materials.In or-der to better satisfy the requirements of low elastic modulus,biological activity after implantation in human body,the preparation of titanium based hydroxyapatite(HA)biological composites by adding hydroxyapatite with pow-der metallurgy has become a research hotspot.Based on the basic properties and existing problems of titanium and titanium alloys,this paper summarizes the research progress of titanium based HA biological composites by pow-der metallurgy such as hot pressing,powder injection molding,spark plasma sintering from the aspects of prepar-ing biological composites to reduce elastic modulus,improve biological activity and corrosion resistance.The rep-resentative cases were listed separately which were preparation for titanium hydroxyapatite biocomposites by syn-thesis of α type,α+β type and β type titanium alloy with HA.Moreover,the challenges faced and suggestions for the development direction are also proposed.
