Metal-ceramic layered materials and composites manufactured using powder techniques

The manufacturing of metal-ceramic composites was investigated as part of subproject ""C3-CerMetComp"" at the ECEMP Excellence Cluster in Dresden. Three different manufacturing technologies were investigated: (i) Thermal spraying for the preparation of metal-ceramic multilayers; (ii) tape casting of layered composites followed by a co-sintering step (in order to prevent defects during co-sintering the sintering behavior of the metallic material was adjusted to the shrinkage behavior of the ceramic); and (iii) hot pressing of zirconia-metal fiber composites with homogenously distributed fibers and subsequent evaluation by means of fracture toughness testing.
