Abstract
This study proposes a method for using thermal explosion to coat the surfaces of diamond particles quickly. This method utilizes the high temperature generated by thermal explosion to promote the rapid sublimation and deposition of Ti powder on the surfaces of diamond particles. This study applied a mixed powder of Ti and diamond particles and conducted vacuum heat treatment. Ni–Al compacts were used for thermal explosion to promote the rapid sublimation and deposition of Ti on the surfaces of diamond particles. Results indicate that Ti rapidly evaporated and deposited on the surfaces of diamond particles after thermal explosion. A composite coating of Ti and TiC on the surfaces of diamond particles formed. The compressive fracture strength and impact toughness index of the prepared Ti–TiC coated diamond particles were 16.0% and 7.4% higher than those of the original diamond particles, respectively.
