Conclusions
-
1.
The degree of hardening and magnitude of the residual stresses resulting from burnishing depend on the chemical composition, properties, and structure of steels. The greatest increase of hardness and residual compressive stresses was observed in steels with a martensitic structure and the lowest in steels with a sorbitic structure.
-
2.
The increase of the fatigue limit and the wear resistance in rolling friction depend on the increase of the hardness and the magnitude of the residual compressive stresses. Hardening improves the operational characteristics for any type of structure, but particularly in the case of martensitic structures.
