Abstract
Numerical modeling of the processes of heat and mass transfer under the action of laser radiation on a titanium surface in a nitrogen medium has been performed. The problem statement includes a system of two-dimensional nonstationary nonlinear equations of heat conduction and diffusion with the corresponding initial and boundary conditions. The problem was solved taking into account the laser beam motion. The character of the distribution of the alloying elements in the zone of laser heating has been investigated. The results obtained make it possible to conclude that the concentrations of the alloying component are essentially inhomogeneous.
