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

High toughness ceramic/metal composite and process for making the same

The surface of a workpiece is provided with a surface layer. Initially, the workpiece is inductively heated by a HF/MF generator to a first temperature and subsequently heated further by a laser beam with coating material being applied to the region of the laser beam in an amount sufficient to form a surface layer on the workpiece. The generator and the laser source are able to operate simultaneously to effect a high quality surface layer of relatively thin thickness.
