The present invention relates to a method for protecting surfaces of components against cavitation erosion and components provided with such cavitation protection surfaces, wherein in the surface a plurality of microcavities is provided which entrap gas such as air; the gas, air, entrapped inside the microcavities expands in the vicinity of cavitation bubbles, forming a gas cushion layer that directs cavitation jets away from the surface, thereby protecting the surface against cavitation erosion; the cavitation having a reentrant or double reentrant inlet design with typical T-shape and T-shape profile
