Abstract

The structure and properties of composite materials based on micropowders of silicon carbide and nanopowders of aluminum oxide and zirconium in the process of hot pressing by electroconsolidation are investigated. The results of researches of the infl uence of structure parameters and phase composition on the microstructure, physical and mechanical properties of silicon carbide-based 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 aluminum oxide and zirconium dioxide into the microporous powder of silicon carbide makes it possible to increase some of the physico-mechanical properties of the obtained composite materials.
