The object of study: technological processes of synthesis of nanosized tungsten carbide powder and zirconium oxide and aluminum and obtaining products from mixtures based on them by elektrokonsolidation. The aim of the research work: the development of physical and technological foundations of obtaining nanopowders mono tungsten carbide, zirconium oxide and aluminum oxide establish the relationship between the technological parameters of the process of synthesis and compaction and the structure and development of the technological basis for production by hot pressing with a direct pass visokoampernogo current (elektrokonsolidatsiya) composite materials with high mechanical properties (hardness, strength, crack resistance) based on zirconium oxide nanopowders with additives of aluminum oxide and tungsten carbide. Development of new materials, including the increasingly important role played by composites, requires the creation of technological bases for their production, which would provide a set of necessary properties (strength, cracks and wear, and so on). The problem of predicting the mechanical properties is a key issue in the overall development of technical ceramics and composites and inseparably linked to the other components of the fundamental problems of a multi-stage 'chemical composition, technology, structure "-" structure - physical and mechanical properties. " Scientific and practical importance of establishing links between the chemical and morphological characteristics of the feedstock, technology and structure - on the one hand and the structure and mechanical properties of composite materials, on the other hand, determined the direction of research and research work.
