POLYCRYSTALLINE CUBIC BORON NITRIDE COMPOSITE SHEET HAVING CONTINUOUS GRADIENT STRUCTURE AND PREPARATION METHOD THEREOF

ZHANG SHAOHE / RONG LINGLONG / ZHAO DONGPENG / KONG XIANGWANG / WU JINGJING / ZHANG HAOYANG / GAO HUA / LI JINCHENG / SHAO MENGYAO / GENG CHANGJIAN

The disclosure discloses a polycrystalline cubic boron nitride composite sheet having a continuous gradient structure and a preparation method thereof. The polycrystalline cubic boron nitride composite sheet consists of a cemented carbide substrate, a continuous gradient layer, and a CBN layer from bottom to top. The continuous gradient layer contains cemented carbide and CBN, a content of CBN increases in continuous gradient from bottom to top, while a content of the cemented carbide decreases in continuous gradient from bottom to top. A volume fraction D of CBN and a volume fraction M of cemented carbide in the continuous gradient layer both satisfy exponential gradient functions. At the same time, the disclosure uses direct ink writing 3D printing technology with slurry to realize the preparation of the polycrystalline cubic boron nitride composite sheet having the continuous gradient structure.
