In this research, SiC/diamond composite coatings were fabricated by a novel procedure that consisted of the electrophoretic deposition ( EPD ) of diamond particles onto graphite substrates followed by chemical vapor deposition ( CVD ) of SiC. Various concentrations of MgCl 2 were employed to increase the deposition rate and uniformity of the deposits during the EPD process by giving a positive charge to diamond particles. The CVD of SiC was found to have a tightly connected diamond‐graphite interface and spherical texture. With higher weight fraction of diamond particles deposits, the wear of steel ball increased, while the wear of SiC coating decreased.
