Abstract Scope |
Ni-based superalloys are crucial in the operation of gas turbine engines. Due to the interaction of environmental deposits and gases with high temperatures during operation, accurate laboratory-scale hot corrosion testing is needed to elucidate the effects of deposit, atmosphere, and temperature on the degradation behavior. The principal aim of this study was to investigate the effects of common hot corrosion test procedures on the results that are obtained. For this study, the effect of Na2SO4 wetting was studied for its ability to affect hot corrosion test specimens downstream in the gas stream. The effect of the addition of steam and SO2 in the gas stream was also studied as testing variables. |
