Results of an experimental research on formation of surface layers from a material with shape memory effect (SME) three-componental structure on the basis of TiNiCu combined method including mechanical activation and a plasma dusting in vacuum are presented. It is shown, that the plasma dusting in vacuum of three-componental system TiNiCu allows to receive surface layers in nanostructure condition practically of any thickness. The structure, chemical and phase structure of blankets TiNiCu provide display SME. The average size of grain of coverings TiNiCu fluctuates within 20-200 nanometers. It is experimentally shown, that superficial modifying TiNiCu raises durability of a steel 45 at multicyclic loading on ~30-45 %, and wear resistance in 2,5 3 times.

The results of experimental studies on the formation of the surface layers of a material with shape memory effect (SME) based on TiNi deposition of Pb-Bi melt at a temperature gradient of 600-1100 °C in an argon atmosphere. It is shown that this method allows to obtain uniform surface layers in nanostructured state and almost any thickness can be used for the formation of coatings on the interior surfaces of products of any shape with the stress concentrators. Structure, chemical and phase composition of the surface layers provide a manifestation of TiNi shape memory. The average grain size of TiNi coatings ranges between 60 ÷ 160 nm.

An interest in NiTi alloys with near stoichiometric composition (55 NiTi) has intensified since they were found to exhibit a unique mechanical shape memory effect at the Naval Ordnance Laboratory some twelve years ago (thus refered to as NITINOL alloys). Since then, the microstructural mechanisms associated with the shape memory effect have been investigated and several interesting engineering applications have appeared.The shape memory effect implies that the alloy deformed from an initial shape will spontaneously return to that initial state upon heating. This behavior is reported to be related to a diffusionless shear transformation which takes place between similar but slightly different CsCl type structures.
