Abstract (English):
A promising direction of strengthening development is a combined strengthening by a surface plastic deformation with the further case hardening. There are considered possibilities for the creation of a multilayer heterogeneous structure with high strength and operation characteristics by a combined impact with a deformation wave and case hardening. The investigation results of the wave deformation strengthening of deposited metal allowing the support of a considerably higher level of material mechanical and operation properties as compared with rolled metal are presented. The results obtained allow recommending a wave deformation strengthening and combined technologies on its basis for operation properties increase of machinery in a wide range.
