Abstract
High-temperature impact on the metal surface in cavitation erosion has been confirmed. Application of dispersion-hardening alloys with an unstable structure is recommended for its elimination. Control of thermal cycle and cladding technique enables a considerable improvement of the cavitation-erosion resistance of the deposited metal.
Keywords: cavitation, erosion, specific energy content, wear-resistant cladding, steel, non-ferrous alloys, relative erosion resistance
