摘要
研究了添加剂(Ti、Mo、Ti N)对高铬铸铁和Al2O3陶瓷颗粒间界面结合行为及断裂强度的影响。结果表明,这3种添加剂均可以改善高铬铸铁与Al2O3陶瓷颗粒间的润湿性,增加了二者之间的界面反应程度,实现了二者间界面的冶金结合,从而使Al2O3/高铬铸铁复合材料具有较高的断裂强度,其中,尤其以Ti的作用最佳。
The effects of additives(Ti, Mo, Ti N) on the interface bonding behavior and fracture strength between Al2O3 ceramic particles and high chromium cast iron were studied. The results show that, these three additives can improve the wettability between Al2O3 ceramic particles and high chromium cast iron, the degree of interfacial reaction between the two is increased, and the metallurgical combination of the interface between the two is realized. Therefore, Al2O3/high chromium cast iron composites have higher fracture strength, especially Ti.
