Abstract

In this study, NiC°CrAlY bond coat and two types of top coat including yttria stabilized zirconia (YSZ) and ceria and yttria stabilized zirconia (CYSZ) were deposited on IN 738LC by air plasma spraying (APS). Hot corrosion behavior of samples in 1000 °C was study using 55wt.%V2O 5-45wt.%Na2SO4 corrosive salt. Characterization and analysis of results was done by employing field emission scanning electron microscope (FESEM) and x-ray diffractometry (XRD). Results ravealed that plasma sprayed CYSZ TBCs exhibited excellent hot corrosion resistance which was superior to that of YSZ TBCs due to strong acidity and high contents of stabilizer.
