Hot isostatic pressing effective in improving ductility of metal plating. Previously hot isostatic pressing used on powder-metallurgy parts and castings but not on electroplated parts. To test idea, copperplated heated to 800 degrees C at pressure of 23,000 psi (160 MN/m2) for 4 hours. When part examined metallographically, completely free from porosity.
