High-temperature interaction between environmental deposits and Ni-based superalloys is of significant importance to the durability of components in aero turbine engines. Recent results have shown that more thorough laboratory testing is needed to elucidate the effects of deposit wetting and consumption on Ni-based superalloys. The principal aim of this study was to investigate the wetting and reaction behavior of hot corrosion deposits on a Ni-based superalloy. For this study, the Na2SO4 deposit was studied due to its perceived ability to affect specimens downstream in the gas stream. The effect of SiO2 addition to the deposit was also studied.
