Metal Dusting Corrosion: Mechanisms and Control

Abstract

The metal dusting corrosion of Fe, Ni and Co and selected Ni-based and Fe-Ni based alloys in CO-H2 environments in the 400-850oC temperature range is discussed. Where possible, a mechanistic interpretation of the results is included. Based on the corrosion mechanism, control strategies are outlined. These include novel alloy development, the use of coatings and the use of additives to the process stream.
