High-temperature oxidation of composite based on double titanium–chromium carbide

The effect of a metallic binder and nickel coating on the high-temperature oxidation resistance of a composite material based on double titanium-chromium carbide is studied. It is shown that the introduction of a Fe–Cr binder decreases the rate of oxidation of the base material, but the maximum weight increment of the samples remains as it is in the initial TiCrC because of the oxidation of binder components. The nickel coating not only substantially decreases the oxidation rate of the composite components, but also shifts the thermal effects toward much higher temperatures. The oxidation occurs in two stages for compact samples, in three stages for the composite material, and in four stages for the composite material with nickel coating.
