Preparation of composite materials based on oxide ceramics by the free SHS-compression

This article deals with a problem relevant for modern industry – the development of new composite materials based on oxide ceramics used in application of protective coatings to parts and cutting tools. The authors proposed the free SHS compression method as a technology for producing such materials; it combines the process of self-propagating hightemperature synthesis of materials and their subsequent high-temperature shear deformation of the resulting products. The influence of free SHS compression process parameters on the process of manufacturing products from the selected research objects has been studied. It has been found that for the tested materials there is an optimal temperature-time treatment interval that allows manufacturing high-quality products. A study of the phase composition and microstructure of the obtained products has been conducted. The paper also studies the physical and mechanical properties of the obtained products, and conducts heat resistance tests in the temperature range of 1000–1300 °С for 10 hours.
