Explanation

The wear phenomenon of solid surface material loss caused by the impact (scouring) of fluid containing solid particles. erosive wear can be divided into gas-solid erosive wear, liquid-solid erosive wear (or slurry erosive wear), liquid drop erosive wear and cavitation wear according to different solid particles and their carrying media. In nature, industry and mine production, there are a lot of erosive wear phenomenon. For example, the erosion of materials in the material conveying pipeline to the pipeline, the erosion of boiler pipes by combustion dust, the erosion of grit blasting machine nozzles by sand particles, the erosion of mud in the mud pump to the pump body and impeller, the dust and erosion of helicopter propellers in the air, and the erosion of rocket engine tail by combustion gas can also be used to clean and strengthen the surface of machine parts, such as grit blasting, shot blasting, etc. The main W factors affecting erosive wear are: the composition, structure and properties of erosion materials, the shape, size and properties of abrasive particles, erosion speed of abrasive particles, erosion angle and environmental factors.
