Erosion and Abrasive Machining

Erosion from solid particle impact steadily degrades the surfaces of pipelines, hydro turbines, and industrial machinery, wearing away material through repeated collisions that, combined with corrosive environments, can accelerate structural failure far faster than either process alone. Researchers use computational fluid dynamics simulations alongside controlled laboratory experiments to predict how particles suspended in water, slurry, or abrasive jets interact with different materials under realistic operating conditions. A central challenge is developing wear-resistant materials and surface treatments that hold up across the wide range of flow velocities, particle sizes, and chemical exposures found in settings like oil and gas infrastructure or hydropower installations. Open questions remain around accurately coupling erosion and corrosion models, and around translating short-term experimental findings into reliable long-term predictions for complex real-world geometries.
