Abstract
After a qualitative description of the rules of formation of laser surface alloys performed by superficial melting of both the predeposited coating and the substrate, numerical and semi-quantitative models rapidly allowing a rationnal choice of the operating conditions are presented. These models have been compared with experimental result. They give the general trends of the heat and mass transfers processes during laser alloying.
