The article contains a block diagram of the mechanical activation process of multicomponent shape memory materials, taking into account the variety of influencing factors. We have proposed to evaluate the reactivity of the sprayed material using the energy criterion (energy intensity), determined by the additivity concept as an energy amount of the raw material and energy accumulated during mechanical activation. Power consumption of the raw material depends on the chemical and phase composition and is determined based on the similarity between the melting energy, plastic deformation and fracture on the thermodynamic characteristics and diagrams of the systems. The energy stored in the MA is determined on the basis of X-ray structural analysis. We have demonstrated that with increasing of grinding precision there is growth in the number of active centers, which enables nanostructurization of surface layers in high-velocity oxygen-fuel spraying (HVOF). According to the study, we have developed practical recommendations for effective implementation of mechanical activation of the shape memory material
