Paper Abstract

Laser cladding by means of direct remelting of allow powders Stellite SF6 and Metco 16C was applied for production of protective coatings on chromium steel substrates of composition close to that of the gas turbine blades which operate in extremely aggressive environment. For sample preparation a 1.2 kW cw CO2 laser with powder jet coaxial to the laser beam was used. Compared to previous experiments the controlled preheating of substrate at temperatures around 500-720°C was applied and resulted in crack-free coatings.
