The controversies surrounding the effect of cavitation heat on material surface has exacerbated the fuzziness of the cavitation erosion process and limits the manufacturing of protective materials. According to this result, the coating achieved simultaneous absorption of mechanical impact energy and thermal energy released by the bubble collapse, while still avoiding crystal overenrichment and resulting in a CE resistance 2 times higher than that of the classical AlCrCoFeNi HEA coating. This design idea of generating different energy restraints or neutralization by surface microstructure's unique reaction patterns provides a completely new route for the manufacture of CE-resistant materials.
