| Popis: | The article proposes an approach to solving the problem of increasing fretting resistance of lock joints of blades for gas turbine engines through the creation of nanostructured topocomposites with the surface layers in a metastable state having a low shear stability in terms of vibrofriction. The authors implement the method of vacuum combined ion-plasma processing, which allows forming the surface layers of the material with mixed amorphous-nanocrystal structure and purposeful controlling the surface morphology. They show that the proposed flow diagram allows developing the required morphology from the arrays of nano-sized conglomerates of the “asperity – cavity” type on the surface. A comparative study of fretting resistance of nanostructured topocomposites in terms of vibrofriction is carried out. It is established that the specificity of their wear is to reduce the wear rate at the initial stage. |
