摘要

The Influence of plasma sprayed NiCr-Cr2O3 and Al2O3-40% TiO2 (A40T) coatings on Inconel 617 are investigated at 900 and 1000 degrees C under mixed salt environment for gas turbine applications. The results revealed that the plasma coated alloy exhibits lower mass change than bare alloy in the Na2SO4 and NaCl salt mixture with and without V2O5. The response to the experimental analysis is statistically evaluated using 2(3) factorial design. Further the exposed samples were analyzed by means of optical image, SEM, EDS and XRD results. The EDS and XRD analysis revealed that the oxides are rich in Ni and Mo on the surface of the samples. The coated samples exhibited better corrosion resistance in A40T when compared to NiCr-Cr2O3 coatings than bare alloy.
