This program evaluated turbine coating materials for resisting hot corrosion and ash erosion effects due to V, S, and alkali metals in residual oils, and coal-derived fuels. Furnace and burner rig tests were conducted to evaluate the performance of NiCrSi alloys, NiCrSi alloys containing additives, Cr-base alloys, and Si-34Cr-23Ta in Na/sub 2/SO/sub 4/, V/sub 2/O/sub 5/ and mixed salt hot corrosion. CoCrAlY, Co-40Cr-8Si, and Cr-20Ni-5Mn-5Si were also evaluated. Tests in gaseous environments containing SO/sub 3/ are planned. 8 figures. (DLC)
