摘要
生物医用Ti合金的植入物为适应人体内部复杂的环境,要求植入物具有高强度、一定的塑韧性和低的弹性模量等优异的力学性能.当自腐蚀电位越高以及腐蚀电流密度越小时,合金的耐蚀性将越好.合金在医用过程中在体内释放的金属离子将越少,对病人造成二次伤害也就越小.对第三代生物医用Ti合金的处理工艺、力学性能和耐腐蚀性能进行综述,以期对材料研究者在生物合金的应用研究方面提供有价值的参考.
Abstract
Biomedical Ti alloy implants are required to have excellent mechanical properties such as high strength,certain plastic toughness and low elastic modulus in order to adapt to the complex environment inside the human body.The higher the self corrosion potential and the smaller the corrosion current density are,the better the corrosion resistance of the alloy is.The less metal ions released by the alloy in the medical process is,the less secondary damage to the patient is.The treatment process,mechanical properties and corrosion resistance of the third generation biomedical Ti alloy were reviewed,in order to provide a valuable reference for material researchers in the application research of biological alloys.
