GLASS-CERAMIC THERMOSTABLE COMPOSITE COATINGS ZrB2-24mosi2-5Y2O3-10AL ON THE SURFACE OF CARBON-CONTAINING MATERIALS
One of the urgent tasks of modern materials science is the creation of new cheaper materials for structural purposes with improved performance characteristics for work in extreme conditions - at high and ultrahigh temperatures in aggressive environments and under erosive influences. One of the directions of creating products with specified fundamentally new properties is the application of functional coatings on the surface of basic materials made using traditional technology. As part of the article, new composite coatings ZrB2-24mosi2-5Y2O3-10al were applied to the surface of a carbon-carbon composite using a multi-chamber detonation accelerator. The influence of formation conditions on the change in the microstructure of coatings has been studied. Optimal technological conditions for the organization of the processes of formation of composite coatings ZrB2-24mosi2-5Y2O3-10al have been established: barrel diameter 16 mm, barrel length 500 mm, spraying distance 80 mm.
