Abstract
PURPOSE: To obtain a ferrous sintered forging of high hardness formed with deep carburized layers in desired parts by molding ferrous material powder by compaction, and forging the molding after sintering the same in a carburizable atmosphere.
CONSTITUTION: Powder of a ferrous material is molded to a desired shape by compaction, and an anticarburizing agent 7 is plated or coated on the prescribed parts of this molding 6. Thence, the green compact molding 6 is placed on a heat resistant receiving tray 10 in such a way that the surface to be carburized exposes to the inside of a sintering furnace, thence the carburized surface 6' is formed in a gaseous atmosphere, the sintered body after the sintering by heating and the carburizing is formed to a sintered forging having prescribed dimensional accuracy, shape and strength. Further, if necessary, it is subjected to induction hardening and the like to have improved mechanical properties. According to this method, the product having high surface hardness and good weldability in combination is obtained.
