Abstract
Abstract The work demonstrates possibility of formation of coatings based on the ZrSi 2 -MoSi 2 -ZrB 2 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 ZrO 2 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.
