Modern approaches to the creation of single-layer and multi-layer high-temperature coatings for the protection of heat-resistant carbon-containing composite materials from oxidation and erosion in the high-speed fluxes of oxygen-containing gases are analyzed. Particularly have been outlined the heat-resistant coatings, the main components of which are either super refractory transition metal borides (ZrB2, HfB2, TiB2) with the addition of carbides (SiC, ZrC, HfC, TiC, TaC), silicides (MoSi2, TiSi2, ZrSi2, TaSi2, WSi2) and nitrides (HfN, ZrN, TiN), or refractory oxides (HfO2, ZrO2), or more complex synthetic compositions based on oxide ceramics. The results of fire gas-dynamic tests of coatings of perspective compositions are presented. The potential architecture of ultra-high-temperature coatings with high efficiency of protective action is justified.

The work demonstrates possibility of formation of coatings based on the ZrSi2-MoSi2-ZrB2 system by the slip-firing method. During oxidation, the coatings form heterogeneous oxide film resistant to high-speed high-enthalpy gas flow due to generation of refractory ZrO2 framework filled with borosilicate glass doped with zirconium dissolved in it. The advantages and disadvantages of the coatings in the system under study are presented.
