    ABSTRACT:
    The structure and properties of composite materials, for gas turbine engines based on nanopowders alumina, zirconium dioxide, and tungsten carbide, in the process of hot pressing by electroconsolidation are investigated. Research results on the influence of structure parameters and phase composition on the microstructure, and physical and mechanical properties of alumina composites obtained by electrosparking (electroconsolidation) are described. It has been established that the formation of a composite structure, due to the introduction of nanopowders of alumina and zirconium dioxide into the nanopowder of tungsten carbide, makes it possible to increase some of the physico-mechanical properties of the obtained composite materials.
