Resumo
The paper presents a study of the effect of different surface hardening methods on the fatigue limit of a number of specimens. The following surface plastic deformation methods were used: pneumatic shot peening, hydro-shot peening, diamond burnishing, and roller rolling. The analyzed batches of circular cross-section specimens made of 30KhGSA, 12Kh18N10T, EI961, 45, and 20 steels with a stress concentrator in the form of a notch. The specimen diameter was 10 mm. It was found that diamond burnishing and roller rolling resulted in a greater increase in the fatigue limit of notched specimens. These hardening methods ensure a more complete distribution of compressive residual stresses along the depth of a non-propagating fatigue crack than with hydro-shot peening and pneumatic shot peening. With the same method of surface hardening, compressive residual stresses of greater magnitude are created in samples made of steels with a higher yield point than in samples with a lower yield point. Based on the results of this study, it was concluded that the criterion of average integral residual stresses should be used to assess the fatigue limit for surface-hardened notched samples. The criterion should be determined by the thickness of the dangerous section, equal to the critical depth of a non-propagating fatigue crack.
