Fabrication of Ni-NiO composites by tape casting

In the processing of metal/ceramic composites, problems associated with interfaces often arise. To help minimize these problems, functionally gradient materials have been developed. In this paper, uniform metal/ceramic composites of varying composition are fabricated via a two-step process. A porous ceramic preform is first made by tape casting. This is then infiltrated with liquid metal. Controlling the amount of porosity in the tape will …
