Formation of nanostructured surface layers from Materials with shape Memory effect TiNiCu in conditions

摘要

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.
