Corrosion-Erosion Behavior of Materials in a Coal-Gasification Environment

Abstract

Materials considered for application in the high temperature gaseous environments that are present in various coal-gasification processes must be resistant to corrosive and erosive wear. Possible interactions between the materials and the gaseous environment that lead to oxidation, hot corrosion, sulfidation, carburization, and metal dusting are discussed. Existing formalisms for predicting erosive wear loss of materials are presented. The need for additional research on corrosion of materials in complex multicomponent gas environments and on erosion of materials in the relevant range of process conditions to develop suitable models for corrosion-erosion behavior of materials is discussed.
