根据外科刃具材料的性能要求 ,设计并制备了用于外科刃具的Ti(C ,N)基金属陶瓷。通过在两种医疗消毒介质中的腐蚀实验 ,评价了该材料的耐蚀性 ,并讨论了其分别在两种消毒介质中的腐蚀机理。结果表明 ,Ti(C ,N)基金属陶瓷具有良好的耐蚀性 ,其在医疗消毒用次氯酸盐溶液中主要为电化学腐蚀 ,而在H2 O2 水溶液中则以氧化腐蚀为主 Ti (C, N) -based cermets for surgical cutting tools were designed and prepared according to the performance requirements of surgical cutting tools. The corrosion resistance of the material was evaluated by the corrosion test in two kinds of medical disinfection media, and the corrosion mechanism of the two kinds of disinfection media was discussed respectively. The results show that the Ti (C, N) -based cermets have good corrosion resistance, which is mainly electrochemical corrosion in the hypochlorite solution for medical disinfection and mainly to oxidation corrosion in the H2 O2 aqueous solution
