Abstract : The report is a study of the destruction of nickel, copper, austenite alloys of iron with nickel and manganese, and 1Kh18N9T and 1Kh13 steels that were subjected to the action of cavitation in molten lead. The same regularities are characteristic for cavitation erosion in liquid metal and water. Destruction with basically a mechanical character is localized in separate surface micro-volumes of the metal. Observation shows a dependence between the hardening of a metal under the action of cavitation in the melt and its resistance. High anticorrosion properties of metals are not a sufficient condition of their resistance during dynamic interaction with a melt. (Author)
