Metal Dusting of Centrifugally Cast Superalloys
View through CrossRef
Metal dusting of three centrifugal cast, heat-resistant alloys was investigated in an environment containing 80 vol% carbon monoxide (CO)+20 vol% H2 at 650, 750, and 850 °C for 500 h. One of the nickel-based alloys experienced localized metal dusting at 650 °C and pitting at 750 °C. Pitting occurred on another alloy at 650 °C. A third nickel alloy was the most resistant to metal dusting, but pitting occurred at 750 °C.
