Metal-ceramic composite material with high toughness and process for its manufacture

摘要

The ceramo-metallic composite material includes a ceramic phase with particles of alumina or of an alumina-based solid solution, a refractory phase comprising titanium nitride and/or carbonitride, and a metallic matrix based on Ni, Co, Fe. The interface between the alumina particles or alumina solid solution and the metallic matrix is rich in nitrogen and in titanium or in compounds thereof.
