Erosion corrosion

Erosion corrosion is a degradation of material surface due to mechanical action, often by impinging liquid, abrasion by a slurry, particles suspended in fast flowing liquid or gas, bubbles or droplets, cavitation, etc. The mechanism can be described as follows: Erosion corrosion is a degradation of material surface due to mechanical action, often by impinging liquid, abrasion by a slurry, particles suspended in fast flowing liquid or gas, bubbles or droplets, cavitation, etc. The mechanism can be described as follows: The mechanism of erosion corrosion, the materials affected by it, and the conditions when it occurs are generally different from that of flow-accelerated corrosion, although the last one is sometimes classified as a sub-type of erosion corrosion.
