The cyclic oxidation resistance and the hot corrosion resistance of three single-crystal nickel-base superalloys and DS Mar M 200(+) are compared. The comparison is made by using burner rig oxidation tests at 2000F (1093C) and tube-furnace oxidation and hot-corrosion tests at 2000F (1093C), 1650F (900C) and 1300F (704C). The rig tests and the tube-furance tests produce similar results with the single-crystal alloys being more oxidation resistant than DS MarM 200. A significant difference between the hot corrosion resistance of these alloys was not observed. All four alloys were extremely susceptible to hot corrosion induced by a liquid deposit.
