Simulation of coating phase structure formation in solid phase synthesis assisted by electron-beam treatment

The model of coating synthesis on an iron substrate under heating by a moving energy source typical for electron-beam treatment has been proposed and analyzed. The problem has been solved numerically. The time and spatial distributions of the temperature and the concentrations of the elements and compounds have been found. The regimes of coating formation from the initial material may proceed in a stationary or non-stationary, self-sustaining or forced regime, depending on the energy parameters that characterize the external source and chemical reactions, as well as on the initial concentrations of the elements and phases.
