Abstract

PURPOSE: To manufacture an iron-base sintered metal with superior mechanical strength by adding a small amount of ferric oxide fine powder to raw material cast iron powder followed by compacting and sintering in a nonoxidizing atmosphere.
CONSTITUTION: Cast iron cutting chips are pulverized, adjusted to a suitable grain size, and mixed with 0.5W<2wt% Fe2O3 powder of ≤325 mesh. This mixed powder is filled into a metal mold and compacted to form a green compact. The compact is then sintered by heating at 1,000W1,200°C in a reducing or inert atmosphere for 10W60min according to the form and size of the compact. Thus, graphite fine powder stuck to the cast iron powder and the Fe2O3 fine powder are allowed to react rapidly and effectively, whereby the Fe2O3 are reduced to active Fe atoms to accelerate sintering and enhance the mechanical strength of the resulting sintered body.
