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
