The mathematical model of the processes of induction weld deposition of powder materials in the initial state of dispersionpowder medium and containing the strengthening phase particles represented by ultrafine or nanosized inclusions of refractory oxides or carbides is developed. The results of the modeling of the contact gaps formation between the particles of the dispersed phase in the elastic compression and the impact of this period on the type of transition of dispersionpowder medium into solid state are described. The methods of implementation of nanosized additives in the coating structure are proposed. The developed model allows the calculation of weld deposition process modes with account for the dispersionpowder materials characteristics and centrifugal forces influence.
