Structure and phase transformations in the surface layers of composite ceramic materials based on the systems (TiN–AlN)–(TiN–Cr3C2) and (TiN–AlN)–(Ni–Cr)–(TiN–Cr3C2) with high-temperature oxidation under conditions of concentrated solar radiation
Results are provided for a study of the formation mechanism and conditions for high-temperature corrosion-resistant coatings, which are formed in air (>1500°C) with cyclic thermal changes under the action of concentrated energy sources. It is established that in composite materials of the systems (TiN–AlN)–(TiN–Cr3C2) and (TiN–AlN)–(Ni–Cr)–(TiN–Cr3C2) a complex oxide film forms that has good adhesion to a base and undergoes further composite oxidation, i.e., it promotes an increase in its scaling resistance.
