Abstract:

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 2000 F 1093 C, and tube furnace oxidation and hot corrosion tests at 2000 F 1093 C, 1650 F 900 C, and 1300 F 704 C. The rig tests and the tube furnace tests produce similar results with the single crystal alloys being more oxidation resistant than DS MAR M 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. Keywords Sodium sulfates.
