摘要
研究纳米TiN显著提高TiC基金属陶瓷刀具耐磨损性能的机理。结果表明 ,纳米TiN在晶界上的分布阻碍了TiC晶粒的长大 ,细化了金属陶瓷组织 ,提高了强度、硬度等力学性能 ,使金属陶瓷刀具的耐磨损性能提高。
The internal mechanism that the adding of nano-TiN can improve obviously the wear-resistibility of cermet cutter is researched.The result show that the distribution of nano-TiN at the grain interface inhibit the growth of TiC grains,so the microstructure of cermet becomes finer and the mechanical properties are enhanced;the wear-resistibility of cermet is improved accordingly.
