Paper Title:
Interpenetrating Network Metal-Ceramic FGM – Preparation and Properties
  Abstract

A new method for processing large flat compositionally graded metal-ceramic parts with connected interpenetrating metal and ceramic network is described. Based on powder metallurgical methods, a metal foam is obtained by slip casting of metal powder slurries on a polyurethane foam, and used as preform to achieve a metallic interpenetration within the composite. The porous metallic preform is infiltrated with a ceramic slip and co-sintered. The metallic part is made from Ni-Cr-alloy, or the P/M superalloy Saratherm 2 and Nimonic 90, the ceramic consists of pure 8Y-ZrO2 or zirconia mixed with ZrSiO4. Composites of nominal same composition sintered without the metal foam preform show no metallic interpenetration.
