In studies of erosion-corrosion in “dry” gaseous environments at elevated temperatures, and in wet aqueous environments at room temperatures, there have been recent attempts at mapping such processes. Such maps show the transitions between the erosion-corrosion regimes and thus can be an aid to materials selection in such environments. By plotting the magnitude of the wastage rate on the maps, as a function of the main process parameters, the conditions under which erosion-corrosion damage is minimized are easily identified. The purpose of this paper is to review the approaches to erosion mapping in aqueous and in dry environments. The work carried out on erosion maps for composites and ceramics will also be discussed. The limitations to existing work on the mapping approaches are also be addressed. It is shown how erosion maps can be a potentially powerful tool in minimizing damage due to erosion-corrosion. Further work which needs to be carried out to extend such approaches is discussed. Finally, the use of such maps to construct materials selection maps for both dry and wet erosion-corrosion processes are illustrated.
