The results of structural studies of partial meltings of casting surfaces of plates made of cobalt alloy MAR-M509 have been presented. The partial meltings were formed with argon or helium plasma beam generated in electric arc. Observations of microstructure revealed presence of phase y and carbides. X-ray diffraction has shown phase y, carbide types MC and M23C6 and scanty amount of hexagonal phase [...].
