Abstract

Numerical modeling of the processes during the alloying of the substrate surface metal layer under pulsed laser radiation is carried out. The proposed mathematical model is used to consider the various processes, such as: heating, phase transition, heat and mass transfer in the molten metal, solidification of the melt. The surface of the substrate is covered with a layer of alloying substance that penetrates the melt. According to the results of numerical experiments, depending on the heating conditions of the substrate, two variants of the formation of the flow structure in the melt and the distribution of the alloying substance are determined.
