Abstract
D-Gun thermal spray technique was used to deposit Cr3C2-NiCr and Cr2O3 coatings on T-11 boiler steel in the present study. Hot corrosion behavior of coated and uncoated samples of T-11 boiler was analyzed for 50 cycles at 900 °C in the simulated Na2SO4-60%V2O5 condition. Kinetics of corrosion was measured by using thermogravimetric studies. Surface and cross sectional analysis has been reported by using XRD and SEM/EDS to know the formation of corrosion products. Uncoated sample has shown spalling and degradation of oxide scale. Cr2O3 coated sample has shown detachment of coating from the substrate after 1st cycle. Cr3C2-NiCr coating has shown the protective behavior as well as corrosion resistance in the reported environment by virtue of protective oxides.
