This is a final report covering high temperature materials for use in a fluidic turbine inlet temperature sensor. This study covered the selection of candidate test materials from already-developed materials and their screening at temperatures in excess of 1400C 2550F while exposed to moderate velocity gases at 400 psia. The gases simulate the environment of a gas turbine engine turbine inlet station with approximately 200 percent excess air of stoichiometric conditions. Materials best surviving the initial screening were subjected to longer tests to narrow the field. The two materials selected for final testing were hot-pressed silicon carbide and platinum-40 percent rhodium.
