Transcripción del resumen del autor. 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 500h. 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
