In order to define the influence of laser beam and laser plasma processing on the performance of body centered cubic steels under the cavitation loading, the samples of chromium steel, carbon steel and low-alloy manganese and nickel steels were superficially remelted by a cw Co2 laser beam in presence or without participation of the optical discharge plasma. Afterwards, the workpieces were subjected to the process of cavitation erosion in the rotating disk facility. The tests carried out revealed multiple - 1.8 to 10 times - increase of cavitation resistance of investigated materials during the incubation period of the destruction. This effect was found to be not decisively linked to the obtained microhardness changes. Both the ability of the samples surface layers to accumulate the energy and the residual stresses trapped within the processed zone were also pointed as features having considerable significance for cavitation resistance of the material.
