氮化钛材是我国首创的人工关节材料,它具有质轻、硬度大、耐磨等适宜的机械性能和生物适应性,是一种较理想的人工关节材料。但对其在体内的腐蚀、吸收和移行等情况过去还未进行过研究。初步研究证明,钛经离子氮化工艺处理后,其硬度成倍提高,耐磨性良好,而且体内耐腐蚀性也明显增强,同时又保留了钛材的基本优点。本实验通过对氮化钛和钛材体植入的动物实验,采用ICP发射光谱法测定了大白鼠的
Titanium nitride material is China’s first artificial joint material, it has the light weight, hardness, abrasion and other suitable mechanical properties and biological adaptability, is an ideal artificial joint material. But in the body of corrosion, absorption and migration and so on in the past have not been studied. Preliminary studies have shown that titanium by ion nitriding process, its hardness increased exponentially, good wear resistance, and the body corrosion resistance was also significantly enhanced, while retaining the basic advantages of titanium. In this experiment, titanium nitride and titanium body by implanting animal experiments, ICP emission spectrometry was used to determine the rat
