▎ 摘  要

NOVELTY - Invention relates to technology of obtaining wolfram carbide (WC)-based ceramic materials as well as to technology of spark plasma caking for obtaining ceramic nanocomposites, processed by electrophysical and electrochemical methods, and can be applied in different fields of science and technology. Method for obtaining nanocomposite of graphene and wolfram carbide includes dispersion of graphene oxide in distilled water with the following addition of water suspension of wolfram carbide nanopowder into obtained suspension, removal of liquid phase from suspension until powder-like mass is obtained, formation of blank from obtained powder-like mass under the pressure and its spark plasma caking. Removal of liquid phase is realised by centrifugation with the following lyophilisation, and graphene reduction is realised in the process of blank spark plasma caking. Graphene content constitutes less than 0.8 wt % of composite material. USE - Chemistry. ADVANTAGE - Method simplification with simultaneous increase of mechanical characteristics of graphene and wolfram carbide nanocomposite.2 cl, 1 tbl, 2 dwg
