CATHODIC ELECTROPHORETIC DEPOSITION OF DIAMOND PARTICLES

Cathodic electrophoretic deposition of diamond particles was performed on Ni, stainless steel, carbon fibers and felts, Si wafers, SIC and T iC substrates. Zeta potential measurements were performed and possible mechanisms of particle charging were discussed. The electrophoretic p rocess was quantified in experiments performed with Ni substrates. The possibility of electrophoretic seeding of diamond particles via the c athodic process has been demonstrated. The deposits were characterized by SEM. (C) 1998 Elsevier Science B.V.
