The paper studies the coating consisting of the Al–Cr sublayer and external Y–Al–O ceramic layer obtained by vacuum-arc deposition for the protection of the VTI-4 (Ti49–11Al–40Nb) intermetallic alloy from oxidation at 750°C. The coating degradation mechanism and phase transformations are studied during their heating in a furnace and thermal cyclic tests. Test results show the stability of the double-layer coating in both cases.
