ABSTRACT Hot corrosion is a serious problem in aircraft, marine, industrial and land-base gas turbines. To obviate these problems, superalloy superfer 800H (Midhani grade) is one of the prominent materials for the high temperature applications. The present work investigates hot corrosion behaviour of superfer 800H exposed to two different molten salt environments Na 2 SO 4 + 60% V 2 O 5 and Na 2 SO 4 + 5% V 2 O 5 + 5% NaCl respectively, at 900oC under cyclic conditions. The weight change measurements made on during the experiments are us...
