Abstract
PURPOSE:To produce a lustrous, satisfactory finished surface for a extremely short time and save a troublesome embedding operation for grain by mixing, molding and sintering cast iron powder and abrasives to provide a composite lap of grain fixed integrally to a base metal of cast iron. CONSTITUTION:Abrasives are added in a predetermined proportion to cast iron powder which will become base metal and mixed uniformly therewith by a ball mill or the like. Then, a dies 9 is filled with mixture powder 8 of cast iron powder 7 and abrasives (grain) 3 which is press molded with a punch 10. A pressed powder molding 11 of the cast iron powder and abrasives obtained in the previous process is charged into a furnace and sintered in reducing atmosphere with or without pressure. The molding 11 may be forged after the sintering by pressurizing in a preheated dies or the like and further subjected to annealing process.
