In this paper, processes of contact melting between steel plates, which arises after feeding the contact pulse of a contact welding machine, are studied, for cases when nanomaterials in the form of carbon nanofibers and powders of refractory metals are being located between the plates. It was established that the addition of carbon nanotubes allows to ensure the passage of contact melting with lower energy costs and to obtain high carbonaceous layers of considerable hardness, and the addition of doping elements makes it possible to control the structure, grainy and physical and mechanical properties of the formed material.
