Research Status of Thermal Damage Inhibition Technology for Diamond

      The thermal damage of the diamond during the preparation process of diamond tools mainly included diamond graphitization, diamond breakage and cracking, and chemical erosion of diamonds. In response to the thermal damage of the diamond, this article introduced the current suppression technologies for diamond thermal damage from three aspects: surface coating of diamonds, adjustment of matrix material properties, and optimization of forming technology. The article also provided prospects for future research directions to provide reference and guidance for the preparation of high-performance diamond tools.
