The problem of interaction nanoparticles (NP) with a surface of materials has recently become especially urgent. This is due to the using NP both as modifying agents of a surface of materials and during treating materials. In particular for fabrication of a different type of openings till operating a hyper thermal gas jet containing nanoparticles. Regulating arguments of a gas stream it is possible to receive one of the indicated processes. It will be noted that the choice of optimal arguments of these processes by experimental methods requires substantial material resources. Hence the application of mathematical modeling methods allowing carrying out prior investigations of NP-surface interaction processes and to save time and economize resources while developing new technologies is quite necessary.

The problem of modeling of the NP-surface interaction processes was considered on different structural levels. For solve this task the finite elements method and method of molecular dynamics are used [1-3]. The numerical investigation allowed to cover the fundamental mechanisms of NP-surface interaction processes and to ascertain the basic parameters, defining the kinetics of this process. In particular at NP-surface interaction processes nanoparticle can be shattered or dive inside of a material, depending on its drop energy of move, temperature and proportion between ultimate strengths of a material and particle. Depending on thickness of a material nanoparticle can as remain inside a material or pass it through. At low-level energy of move the particle is simple adheres to a surface of a material or recoils from it. At shock of particle at bevel way to a surface it can pull out a slice of a material of a surface, which one can fly away. The results of accounts are used at designing some device.
