Abstract

The article is devoted development of technologies of the superficial strengthening of details of machines as billows by creation of the combined multi-layered wearproof coverages with the set properties. The got results present practical interest for technological developments which provide forming of coverages with necessary operating properties for the different terms of work of details of machines, and also information about possibility of change of properties of coverages. Causing of electro-spark coverages increases operating firmness of details of machines in 3-6 times.

Keywords

superficial strengthening, details of machines, electro-spark alloying, surface plastic deformation, wearproof coverages.
