通过分析镧参与金属胎体 /金刚石复合材料界面反应的热力学及动力学条件 ,指出在本试验烧结条件下 ,镧参与反应的热力学条件已得到满足 ,可以直接或间接参与金属胎体与金刚石颗粒之间的界面反应 ,但在不同的工艺条件下 ,镧的作用程度不同。 By analyzing the thermodynamic and kinetic conditions of lanthanum participation in the metal matrix / diamond composites interface reaction, it is pointed out that the thermodynamic conditions of the lanthanum participation reaction have been satisfied under the experimental conditions of the sintering, which can be directly or indirectly involved in the metal matrix and the diamond particles Between the interface reaction, but in different process conditions, the role of different degrees of lanthanum.
