It is shown for the first time that the presence of porous space in cutting-tool ceramics makes it possible to influence, through water absorption, the performance of diamond machining of such ceramics and, first of all, improve their machinability. The effective duration of water pre-saturation of oxide-carbide ceramics has been found to be 48 h. For lower-porosity ceramic materials the saturation period is longer, e.g., it is 96 h for oxide ceramics and 192 h for cermets.

工具复合材料的孔隙率和吸水性是提高超级磨料砂轮耐磨性的因素。第3部分。刀具陶瓷复合材料

首次表明,在刀具陶瓷中存在多孔空间,可以通过吸水影响此类陶瓷的金刚石加工性能,并首先改善其可加工性。已经发现,氧化物-碳化物陶瓷的水预饱和的有效持续时间为48小时。对于孔隙率较低的陶瓷材料,饱和时间较长,例如,氧化物陶瓷为96小时,金属陶瓷为192小时。
