摘要：
The powder surface coating technology might endow the powder with new physical and chemical properties. By electrophoretic deposition technology, diamond powder was modified on the surface coating of WC powders. The core-shell structure of diamond and the coating between diamond powder and WC powder were analyzed by different characterization methods. The influences of diamond powder content on coating effectiveness were studied, and the bonding strength among powders was compared under different coating processes. The results show that when the mass ratio of WC powder to diamond powder is as 6:1, the coating effectiveness is the best. The strong bonding force among the modified powders comes from the chemisorption formed by covalent bonds such as COO-W and C-O-W and the physical adsorption formed by van der Waals force. © 2024 Chinese Mechanical Engineering Society.
