Synthesis of Composite Material 2(CrxTi1−x)AlC by the SHS Method for Heat-Resistant Products and Coatings

The composite material 2(CrxTi1-x)AlC was obtained using the method of self-propagating high-temperature synthesis. The material can be used to produce heat-resistant products and coatings. The synthesis is organized as a layered structure from a mixture of powders Ti + C/Crx + Ti1−x + Al + C/Ti + C. Where the mixture Ti + C is a heat donor and the mixture Crx + Ti1−x + Al + C is acceptor. By changing the ratio of layer thicknesses, it is possible to control the temperature, the propagation velocity of the front, the phase composition and the microstructure of the material. A material containing a large amount of the target phase Cr2AlC has been synthesized. The thermal-oxidative stability of such a material is maximal. Adding titanium to the Cr + Al + C mixture reduces it. By this method, two products can be synthesized at once: TiC and Cr2AlC.
