  ABSTRACT: In this work, TiAlN and AlCrN coatings were deposited on ASTM-SA213-T-22 boiler steel using Balzer’s rapid coating system (RCS) machine (make Oerlikon Balzers, Swiss) under a reactive nitrogen atmosphere. Cyclic oxidation studies in molten salt environment were conducted at 900°C temperature in the laboratory using silicon carbide furnace. The weight gain was measured after each cycle and visually examined the surface morphology of the oxidized samples was studied using FE-SEM with EDAX attachment and XRD analysis. The results obtained showed the better performance of TiAlN coated T-22 boiler steels than the AlCrN coated and uncoated T-22 boiler steel.
