Abstract

A model has been developed to establish the boundaries on erosion-corrosion maps, where increases in erosion and corrosion are represented by increases in velocity and temperature respectively. The maps show the transitions through the regimes as functions of the main erosion-corrosion variables. The effects of additional parameters such as alloy corrosion resistance and particle flux on the transition boundaries on the maps are simulated in the model. This paper outlines the preliminary work which has been carried out on the mathematical algorithms used to calculate the transition boundaries. The variations in the location of the boundaries with target and particles properties are illustrated. Future development of the maps is discussed in terms of extension of the erosion-corrosion algorithms, and applications to in-service erosion-corrosion problems.
