Many engineering alloys display good high temperature corrosion resistance. However, when they are used in corrosive environments where they are subjected to erosion also, the corrosion resistance has been adversely affected. The phenomenon known as erosion-corrosion is complex and requires detailed investigation of how the erosion and corrosion kinetics interact and compete. At the Kentucky Center for Energy Research Laboratory, an erosion-corrosion tester was constructed. The tester was used to perform some preliminary erosion-oxidation tests on 2 1/4 Cr-1 Mo steel at the 500-600° C temperature range using alumina abrasive at low velocities. In the erosion and oxidation conditions imposed on the alloy, the erosion-oxidation rate data and the morphology of the exposed surfaces are consistent with oxide chipping and fracturing being the mode of material loss.
