Oxidation and Hot Corrosion of Some Advanced Superalloys at 1300F to 2000F (740C to 1093C)

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.
