特征为在磨削期间微破裂的单晶金刚石或CBN
摘要：
本发明涉及一种特征为在磨削期间微破裂的单晶金刚石或CBN。具体地，本发明涉及一种超硬磨料材料，所述超硬磨料材料可包含具有不规则表面的超硬磨料晶体，所述超硬磨料材料还包含在所述超硬磨料晶体内的多个结构缺陷或者具有层状或片状微结构。当用作磨削材料时，所述多个结构缺陷可造成微崩裂。所述超硬磨料晶体选自立方氮化硼、金刚石和金刚石复合材料。还提供了制造氮化硼超硬磨料材料的方法。
摘要（英）：

The invention relates to single crystal diamond or CBN featuring micro-fracturing during grinding, and particularly relates to a superabrasive material that may comprise a superabrasive crystal havingan irregular surface. The superabrasive material further comprises a plurality of structure defects within the superabrasive crystal or has a layered or laminar microstructure. The plurality of structure defects may cause micro- chipping when used as grinding materials. The superabrasive crystal is selected from a group of cubic boron nitride, diamond and diamod composite materials. A method of making boron nitride superabrasive materials is also provided.
