The Production of Porous Ferrous Components by Extensions of the High Voltage Discharge Forming Process

  • D. J. Williams
  • W. Johnson

Summary

Extensions of the high voltage discharge forming process for the manufacture of porous compacts are described. They include the manufacture of tubes, the addition of both a quasi-static and dynamic uniaxial pressure to the discharge process and the manufacture of composite solid porous components.
