A new method for coating diamond particles was proposed.By utilizing the high temperature generated by the thermal explosion reaction,the volatile substances in the thermal explosion sample are induced to sublimate and deposit on the surface of diamond particles.The Ti-Si-C system as an example for conducting thermal explosion reactions was took.The results indicate that the high temperature generated by the thermal explo-sion reaction can induce a large amount of Ti volatilization.Ti deposits on the surface of diamond particles and reacts with the C element on the surface of diamond particles to form TiC.Finally,a Ti-TiC composite coating is applied to the surface of diamond particles.
