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.

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.

Shape Memory Behaviour

At room temperature, Fe-15Mn-5Si-9Cr-5Ni alloys are usually austenitic and the application of a stress induces a reversible martensitic transformation leading to a shape memory effect (SME). However, when a ribbon of this material is obtained by melt-spinning, the rapid solidification stabilizes a high-temperature ferritic phase. The goals of this work were to find the appropriate heat treatment in order to recover the equilibrium austenitic phase, characterize the ribbon form of this material and evaluate its shape memory behaviour. We found that annealing at 1050°C for 60 min, under a protective argon atmosphere, followed by a water quenching stabilizes the austenite to room temperature. The yield stress, measured by tensile tests, is 250 MPa. Shape-memory tests show that a strain recovery of 55% can be obtained, which is enough for certain applications.
