PURPOSE:To provide a hard composite powder having an excellent abrasion resistance and well adapted to be used as an abrasive powder in cutting and grinding, by coating the surfaces of a silicon carbide powder having a specified particle size with thin diamond films. CONSTITUTION:Diamond coating layers having an average thickness of 0.1-50mum are formed on the surfaces of a silicon carbide powder having an average particle size of 5-50mum to obtain a hard composite abrasive powder for cutting and grinding. The diamond coating layers can be formed by vapor phase synthesis using a common chemical vacuum deposition device to achieve a cost reduction.
