摘要：

The cyclic oxidation resistance and hot corrosion resistance of three single crystal nickel-base superalloys and DS Mar M 200 are compared. The comparison was 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 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.
