Abstract

This paper presents experimental results on obtaining bulk samples of Ti–Al–B4C materials by using the method of cold gas-dynamic spraying from a mixture of monopowders in a system of separately operating dispensers, followed by heat treatment. The parameters allowing the development of effective methods for creating products by the additive method are studied and tested. It is shown practically and theoretically that metal plastic particles in the composition of a prototype blank formed by the method of cold gas-dynamic spraying can act as a sacrificial component for the formation of high-temperature borides and titanium carbides, which after heat treatment leads to strengthening of the bulk composite material in the absence of significant shrinkage, maintaining low porosity and continuity of the structure.
