The combined effects of corrosion by fluid and erosion by particles, in equipment such as pipes, vessels and pumps, can have significant economic impact on industrial processes in mining, hydrometallurgy, offshore exploitation, and generally in the transportation of solids, fluids and slurries. Typically, materials are chosen for these applications on the basis of either their resistance to erosion/abrasion phenomena, or their corrosion behaviour. This study considers the combined effects of the two degrading processes on carbon and stainless steels. Alloys containing various elements (including Ni, Cr, Cu) were tested in order to establish the influence of different alloying elements. In order to make proposals for the design of new grades, reliable tests were needed to control the parameters of both corrosion and erosion. These were found to be best provided with consideration of electrochemical and hydrodynamic aspects of the erosion-corrosion processes. This final report concerns the electrochemical behaviour of carbon and stainless steels under erosion-corrosion conditions, focussing on the results which illustrate the conclusions derived from the tests.
