Activities are reported in a program to provide 1000-hour engineering data on the corrosion/erosion deterioration of gas turbine materials U 700 and IN-738 exposed to the exhaust gas from a pressurized fluidized bed combustor. The results show that on the leading edges of the specimens there was deposition, corrosion, and erosion all occurring in the same area. It is reasonable to expect that corrosion and erosion might occur simultaneously. But the occurrence of erosion and deposition in the same area is unlikely except if there was a significant change in the gas velocity during the test. This was the case for the 100 hour shakedown test since the mass flow through the turbine test section decreased significantly after the first 50 hours due to plugging of the inlet orifice of the turbine test section upstream of the cascades.
