Abstract

The hydro blasting influence on an endurance limit of cylindrical specimens with circular cuts of a semicircular  profile of 0,3 mm radius under bending and stretching-compression in a case of symmetric cycle has been examined. Specimens of 10 mm diameter for fatigue tests were made of steels 30ХГСА, 12Х18Н10Т, ЭИ961,45 and aluminum alloys В93, Д16Т.The influence of surface hardening on an endurance limit of specimens with cuts was valuated by two criteria: residual stresses on the concentrator surface and the average integral residual stresses calculated through the part’s dangerous section surface layer thickness equal the critical depth of a non-propagating fatigue crack.

On results of residual stresses and specimens with cuts endurance limits determination it’s been stated that coefficients of surface hardening influence on an endurance limit increase under bending and stretching-compression by two criteria are approximately equal. Besides, the coefficient of the influence by the average integral residual stresses criterion changes within essentially lesser limits than the coefficient of the influence by the residual stresses on the concentrator surface criterion. So the average integral residual stresses criterion should be used for the evaluation of a surface hardening influence on an endurance limit of parts with concentrators.

On an example of specimens within and without peening in a dangerous section it’s been shown that peening doesn’t influence the endurance limit of a surface hardened part. The compressive residual stresses only influence the endurance limit of these parts.
