Erosive corrosion, i.e. erosion, is a phenomenon of metal loss between a metal surface and a fluid due to high-speed relative motion, and is the result of mechanical erosion of the material. Erosion is widely used in mining, metallurgy, water conservancy, petrochemical industry and other industries. Flow components such as pipelines, pipes, valves, pumps, etc. of various facilities exposed to moving fluids are subject to erosion damage, especially in multiphase flows containing solid phase particles.
