The paper presents a complex method of forming the surface-modified layers of materials with shape memory effect, including high-speed flame spraying of powders based on TiNiCo; subsequent thermal and thermomechanical treatment allows the formation of surface layers of nanosized state that have a high level of functional, mechanical and performance properties; it is shown that the complex processing with a layer of TiNiCo allows a reduction of the porosity of the coatings and increases the

It is found that, after treatment with high-speed flame spraying powder shape memory TiNiCo, steel has an increase in cycle life by 30% -40% in a cycle fatigue and 3 -3.5 times durability. Based on comprehensive research into the metallophysical surface-modified layer, new information is obtained about the nanoscale composition.
