    Ironbase P/M parts can be infiltrated with copper or a copper alloy by placing slugs of the infiltrant (which has a lower melting point than the porous body) on the compact prior to sintering. Upon melting, the infiltrant is completely absorbed as a liquid into the pores by capillary action to produce a component with a composite structure.

  • Powder Metallurgy Processing

    Feb 28, 2001· Sintering: Sintering is the process whereby powder compacts are heated so that adjacent particles fuse together, thus resulting in a solid article with improved mechanical strength compared to the powder compact. This "fusing" of particles results in an increase in the density of the part and hence the process is sometimes called densification.

  • Powder Metallurgy

    Powder metallurgy uses sintering process for making various parts out of metal powder. The metal powder is compacted by placing in a closed metal cavity (the die) under pressure. This compacted material is placed in an oven and sintered in a controlled atmosphere at high temperatures and the metal powders coalesce and form a solid.
