Abstract

The influence of high power CO2 laser beam parameters on the process of the laser elevating of cavitation resistance of steels was investigated. The samples of structural carbon steel and corrosion resistant chromium steel were melted superficially with the laser beam and subsequently subjected to the cavitation loading. It was discovered, that the power distribution in the cross section of the laser beam was of the great importance for the elevating of the cavitation resistance of the steel surface subjected to the multipath scan processing. The dependence of the erosion resistance of the tested materials on the frequency of the laser pulses as well as on the power of the beam was also discussed.
