由于钛及钛合金具有优良的生物相溶性、耐蚀性和高的比强度,作为生物用金属材料越来越受到人们的关注。人们对作为生物材料的钛合金不但要求其成分组成中不含有毒及过敏元素,而且要求其应具有与生物体相适应的力学性能、超弹性以及形
As titanium and titanium alloys have excellent biocompatibility, corrosion resistance and high specific strength, as a biological metal material more and more people’s attention. People as a biological material of titanium alloy not only requires its composition does not contain toxic and allergic elements, but also requires it should be compatible with the organism mechanical properties, superelastic and shape
