Formation of superficial nanostructured layers from materials with EFM on details of machine building appointment as a basis of resource-saving technologies

On the basis of damageability analysis of blades of ocean vessels water propellers the expediency of superficial modifying for maintenance the reliability and resource prolongation is shown. As resourcesaving technology superficial modifying of ocean vessels steel blades by materials with effect of form memory (EFM) on the basis of TiNi is offered. Formation of superficial nanostructured layers from materials with EFM is made by plasma dusting of mechanically activated powder TiNi. Results of research the intense-deformed condition of water propellers (on example of motor ship «Concord», Novorossiysk sea shipping company) with surface layer from TiNi, shown decrease in pressure of surface layer as the result of TiNi martensite structures formation. Experimental researches of samples with superficialmodified layer in the conditions of multicyclic stressing and influences of sea water have confirmed the durability increase.
