Erosion-corrosion is a complex mechanism of material degradation resulting from interactions between electrochemical and mechanical processes. The consequences of erosion-corrosion are severe with economic penalties resulting from premature failure of components, increased downtime and increased maintenance costs. This paper assesses the efficiency of two commercial corrosion inhibitors in reducing material damage occurring as a consequence of erosion - corrosion processes. An assessment of the damage is made using gravimetric techniques, electrochemical measurements and visual observation. This paper identifies the role that inhibitors can play in reducing damage, in addition to that caused by corrosion processes alone. The performance of inhibitors in these extremely aggressive erosion-corrosion conditions is discussed in relation to their ability to maintain carbon steel degradation at an acceptable level.
