Thermophysical analisis of modification of the surface of the workpiece by laser radiation by M. N. Vereschagin, S. N. Tselueva, M. Yu. Tseluev

“…The paper presents a thermophysical analysis of modifying the surface of a workpiece by laser radiation due to the melting of a layer of a doping substance previously deposited on the surface of the base metal.The process of heating a two-layer metallic system with a laser pulse with a normal distribution of power density over the beam section is considered. …”
