This book presents advanced laser and hybrid plasma-laser technologies, covering mathematical models of thermal processes, microstructure evolution, and mechanical properties across major metal groups. It explores laser-plasma interaction dynamics, absorption efficiency, and thermal field calculations under pulsed and continuous heating. Surface layer characteristics are examined alongside practical applications including laser-based stiffening, thermo-deformation hardening, sheet metal forming, diamond-containing composite coatings, laser-powder surfacing, and surface treatments like cleaning and nitriding. The content reflects the combined expertise of the Igor Sikorsky Kyiv Polytechnic Institute and the Paton Electric Welding Institute.
