Abstract: The technology to deposit diamond coatings on cemented carbide powder by using electro-phoretic deposition method was investigated. The effect of the mass fractions of cemented carbide and MgCl₂·6H₂O on the quality of the coating was studied, and the prepared powders were characterized. When the masses of the cemented carbide powder, the diamond powder and MgCl₂·6H₂O were 28.0 g, 4.0 g and 1.0 g, respectively, the prepared diamond coating was uniform and good in density.
