N2 - The environments in which erosion-corrosion occurs in advanced coal-conversion systems are complex and dependent on a wide variety of variables; in some, such as fluidized beds, wastage is due to large concentrations of slow moving particles; the effect of preoxidation of Incoloy 800H in these environments has been investigated to ascertain the potential benefit of such a pre-treatment; since the extent of erosion-corrosion in such conditions is dependent on the erosion and corrosion parameters, the effects of temperature and velocity were investigated for both pre-oxidized and as-received specimens; the results are discussed in terms of the existing erosion-corrosion results in fluidized bed environments; a map of the process is proposed, which shows the transition from erosion-dominated to corrosion-dominated behavior, and the method of determining the boundaries of such a map is outlined; the present erosion-corrosion data are incorporated on the map, from knowledge of the kinetic and micrographic analysis.
