We have developed a flow chart for structure and architecture of multilayer surface composition made of multicomponent materials with shape memory effect (SME materials) for different purposes. These compositions have different temperatures of phase transformations. Complex technology of surface composition was carried out in a proprietary installation in conditions of complex high‐energy effects. These effects included mechanical activation of deposited powder material, high‐velocity oxygen fuel spraying with the subsequent thermal, and thermomechanical treatment in a single vacuum cycle with the ability to supply powder to different zones of the gas flow. The deposition sequence of functional layers, their composition, thickness, structure‐phase state, and dispersity are determined by operating conditions and control of the processing mode. For example, surface composition, “Steel‐Ni‐TiNiZr‐TiNiCo,” shows that the use of SME materials allows to create a surface composition, which is functionally oriented not only to improve the performance properties, such as wear strength and corrosion resistance, but also to improve durability and vitality because of the special properties of materials with shape memory composition and architecture. Experimental studies have demonstrated the effectiveness of technologies developed in improving the performance properties.
