Protection of Orthorhombic Alloy by AlCrN Coating

Abstract:

The oxidation behavior of AlCrN coating deposited on Ti-25Al-12.5Nb-6Mo-0.48V alloy was investigated at 700 °C and 800 °C in static air. Oxidation in air indicated that the uncoated alloy exhibited poor oxidation resistance due to the formation of TiO₂ scale, but the major oxide in the oxidized coating was chromia and alumina and the TiN layers were also observed beneath the coating. No sign of degradation and no scaling of the coating was observed after oxidation.
