Cavitation effects on ship propellers lead to increased erosion and a loss of efficiency. In the cavitation process vapour cavities occur and dissolve by implosion. Short-term but considerable side effects in this course are extremely high accelerations, temperatures and pressures. They result in a damage on the surface of solid objects, like e. g. ship propellers, where in the course of time larger particles break away from the surface. Nevertheless, a detailed scientific explanation for this effect does not yet exist.
