针对碳化物颗粒复合会导致氮化硅复合材料相组成发生变化的缺点，对过渡族金属氮化物颗粒（主要是ＴｉＮ）增强氮化硅陶瓷刀具的优点进行了全面分析．分析表明，氮化物颗粒不仅比碳化物颗粒与氮化硅有更好的相容性，而且可以固溶烧结过程中气相里的碳和氧，因此会有效降低氮化硅基体的碳化，这为无惰性气氛保护烧结提供了可能．另外，氮化物颗粒的引入对提高复合材料火花放电加工性及耐磨性能亦有很大帮助．
Aiming at the defect that the phase composition of the silicon nitride composite changes due to the carbide particle composite, the advantages of the transitional metal nitride particles (mainly TiN) enhancing the silicon nitride ceramic cutting tool are comprehensively analyzed. The analysis shows that the nitride particles not only have better compatibility than carbide particles and silicon nitride, but also can dissolve the carbon and oxygen in the gas phase in the sintering process, thus effectively reducing the carbonization of the silicon nitride substrate, which is No inert atmosphere protection sintering possible. In addition, the introduction of nitride particles to improve the composite spark discharge processability and wear resistance is also very helpful.
