Title: Production of iron-copper powder metallurgical product
Inventor: KONO MASAKI
IPC: B22F3/093
Filed: 1991-02-12
Abstract: PURPOSE:To increase the strength of an iron-copper sintered member by subjecting a powder mixture, where a specific percentage of powdered lubricant is mixed, to vibration packing. CONSTITUTION:A powder mixture prepared by adding a powdered lubricant to a ferrous powder by 0.05-4wt.% and mixing them is filled into a compacting die by means of vibration packing. In order to perform the filling with superior flowability, a powdered lubricant for metal powder is used. By exerting compaction at extremely low pressure at the time of filling and applying electromagnetic or mechanical vibration by dry process, compaction can be done with superior transfer characteristics in the edge part. The compacting die filled with the powder is heated and sintered in a reducing atmosphere, in an inert atmosphere, or in vacuum. After drawing from the die, a coppery infiltration agent is infiltrated into the pores of the resulting sintered compact to increase strength.
