Abstract : In the paper the investigations of cavitation erosion of 2H13 and 1H18N9T steels superficially remelted by laser beam arepresented. The experiments were carried out at the incubation period of the erosion. Rotating disk facility was used for generation of the cavitation loading. Influence of the parameters and processing condi-tions on the increase of cavitation erosion resistance was assessed. It was established that martensitic structure in 2H13 steel, created due to rapid cooling within the narrow path of the remelting did not lead to durable improvement of the metal resistance to cavitation attack. It was also stated, that strain-hardening of the remelted layer manufactured in 1H18N9T steel as well as the residual stresses relaxation in course of the pulse radiation processing are most profitable for increasing of the caviation resistance of the latter material.
