In studies of elevated temperature erosion, the performance of various materials has been investigated in a wide range of exposure conditions. Material performance has been shown to be dependent on erosion-corrosion conditions, determined by properties of the impacting particle, the temperature and the composition of the gaseous environment. Changes of the ranking order of wastage rates of various materials, as a function of the process conditions, is a common feature of the results to date. Such observations can make materials selection decisions, for elevated temperature erosion resistance, a fairly arbitrary exercise.

In recent years, there has been significant interest in mapping the erosion of materials at elevated temperatures. Such maps demonstrate the transitions between the erosion regimes as a function of the main process parameters. More recently, for erosion of composite materials, they have also been used to identify the magnitude of the wastage rate.

The object of this work has been to develop a simple rationale for construction of materials performance maps for exposure of materials to elevated temperature erosion conditions. The results used to construct the maps have been generated from literature on the performance of materials in laboratory simulated fluidized bed conditions. It is shown how 'materials selection' maps can be constructed for elevated temperature erosion resistance based on this approach.
