TiC基金属陶瓷配方的正交试验研究

THE ORTHOGONAL EXPERIMENTAL STUDY ON COMPONENTS OF TiC-BASED CERMET

通过正交试验法对TiC基金属陶瓷进行成分研究,选取抗弯强度为试验指标,进行极差分析,获得了最佳的TiC-WC-Cr3C2-Co-Ni-Mo金属陶瓷试验配方A2B3C1组合。试验表明Mo含量的增加使环形相增厚;Mo含量和Co/Ni含量比为抗弯强度的两个主要成分影响因素。

The best components A2B3 C1 of TiC-based cermets （TiC-WC-Cr3 C2-Co-Ni-Mo） were obtained through orthogonal experiments which were taken the transverse rapture strength （TRS） as reference index. It was presented that the surrounding structures were thickened as the Mo content increased, the Mo content and the Co/Ni ratio were the main factors for improving the transverse rapture strength of TiC-based cermet.
