Purpose: Results of laser treatment at cryogenic conditions and its influence on microstructure, microhardness and cavitation resistance of the SUPERSTON alloy are presented in this paper. Design/methodology/approach: New method of the laser remelting specimens diped in liquid nitrogen made by the CO2 laser with 4000 W laser beam power and scanning velocity 0.5 and 1.0 m/min was employed. Observation microstructure was carried out by scanning electron microscope. Hardness of cross-section of the surface layer has been measured by the Vickers microhardness under load 0.49 N. Cavitation test in the water using rotating disc facility was done. Findings: Laser remelting let obtain fine microstructure in surface layer and increase of microhardness and cavitation resistance, compared to casting the SUPERSTON alloy. Research limitations/implications: The future investigations connected with environment conditions should be extend of internal stresses in the SUPERSTON alloy after laser remelting at cryogenic conditions. Practical implications: Obtained results point at possibility of the increase hardness and cavitation resistance of the parts worked in cavitation conditions. Originality/value: The propose laser treatment at cryogenic conditions could be used for surface consolidation of the copper alloys applied for ship propellers.
