Relative movement between metals and environment has an effect on rate of corrosion, unless both anodic and cathodic processes are activation controlled1. Erosion- corrosion is the conjoint action involving corrosion and erosion in the presence of a moving corrosive fluid, leading to accelerated loss of material2. Erosion-corrosion can occur in different situations: in absence or presence of solids and gases. Hence, there is no widely acceptable mechanism of erosion corrosion. However, there are suggestions that the corrosion process is enhanced by increased mass transfer and/or mechanical force impacts on the surface1, 3. Therefore, models to predict erosion corrosion are not readily available. Experimental studies are best way to predict occurrence of erosion-corrosion.
