In the present time the additive technology of synthesis of layered composites that have been produced by precision metallurgical methods of consequent deposition of 2D Si, C, B crystal streng-thened metallic nanofilms using CVD, epitaxy, spraying and laser sintering powders. Basing on the molecular dynamics method the study of thermic evolution of metallic (Ni, Ti, Al) nanofilms has been carried out. There has been revealed the nature of generation and activation kinetic processes, initiated structure transformation and loosing the thermostability of functional unities of two di-mentional transition metallic systems deposited on grapheme (G) substrates. Thus there has been formed by chemical bonds the specific interfaces as the functional unified low-dimentional sys-tems. It was shown, that for all systems concerning in present in-vestigations the increasing temperature for G/Ni and G/Ti, up to 3700K and for G/Al up to 2200K double coating of graphene caused the rising twice as far elongation of the films in the zigzag directions in comparison with their elongation for one side graphene coating. At a sufficiently high thermal stable of a chemo sorption-type interface Me films (Ni, Ti located on the surface of G sheet), their integral stability with respect to the plane of normal diffusion perturbations could be retained and its functional electronic structure (Dirac cone) also be restored via the intercalation doping alloying with the additional layer of sp metals (Al) and transition metals with completed d orbitals.
