Summary on Grant Application Form |
|
Erosion-corrosion by solid particles in aqueous environments occurs in many industrial processes which range from alumina processing to oil and gas production. Although there have been many studies carried out in this field, there have been few that have concentrated on identification of the parameters which determine the transitions between erosion-corrosion regimes. Such transitions have been established for erosion by solid particles in dry oxidising environments. This work will study erosion-corrosion of materials for temperatures up to 120C. Transitions between erosion-corrosion regimes will be achieved by selection of metals and environments in which either a thin (passive) or thicker (precipitated) oxide film is formed at relatively low temperatures. In such a manner, the effects of a wide range of aqueous erosion-corrosion variables on the transitions between the main erosion-corrosion regimes will be evaluated. The results will be used to ascertain whether electrochemical techniques can cause and define transitions between erosion-corrosion regimes. The results on the effects of the main variables will be compared with those obtained for erosion in dry oxidising environments. A further aim of the work is to plot such results on erosion-corrosion maps where the change in aqueous erosion-corrosion regime is given as a function of the main erosion-corrosion variables.
