The structure of surface layers of the hypoeutectic silumin after laser doping by mixture of the copper and cobalt powders are studied using methods of X-ray phase and metallographic analyses. The possibility of the influence on the phase composition of the treated layer and its dispersivity by changing the conditions of laser radiation and ratio between the alloying species in the mixture are demonstrated

Key words: quasicrystalline phase, phase equilibrium diagram, laser alloying, density of irradiation power.
