摘　　要：目的:在不同氮分压下于纯钛表面采用等离子镀膜技术镀制TiN膜后,检测薄膜的结合力、硬度、耐磨性与生物安全性。方法:采用等离子镀膜机在纯钛试件表面沉积TiN薄膜后进行膜-基结合力检测,硬度、耐磨性检测和生物安全性实验。结果:提高氮分压可以增加TiN薄膜与纯钛基体的结合力,硬度和耐磨性检测表明TiN膜可以承受日常口腔刷牙的磨耗。生物相容性实验表明TiN膜无细胞毒性,安全可靠,可以应用于人体。结论:TiN膜可以承受日常口腔刷牙的磨耗且无细胞毒性,安全可靠,可以应用于人体。Objective： To analysis the adhesion, hardness, wear resistance and biological safety of TiN film. Meth- ods： The TiN film was measured the film -- bonding, hardness, wear resistance and biological safety. Results： Im- proving nitrogen pressure could increase the TiN film with the pure titanium substrate adhesion. Hardness and wear resistance testing showed that the TiN membrane can withstand daily oral brushing abrasion. Biocompatible experi- mental results showed that the TiN film had no cytotoxicity. It was safe, reliable, and can be applied to the human body. Conclusion： TiN film can withstand daily oral brush wear. TiN membrane was safe, reliable, and can be ap- plied to the human body.
