Under consideration is a mathematical model of the alloying process of the metal surface by the pulsed laser radiation. The dependence of the surface tension on the surface-active impurities in the melt is analyzed. The numerical simulation enabled to determine the possibility of development of flows and distribution of the alloying material into the metal.

Keywords:
metal alloying, laser radiation, convective heat and mass transfer, numerical simulation.
