Abstract

The influence of technological heredity on the strength of a paddle lock under cyclic loading is conside-red. An analysis is made of the distribution of surface re-sidual stresses in the samples during surface hardening us-ing glass and steel microspheres. The analysis of the stress-strain state of the surface layer of the padlock of the blade in the initial state and after surface hardening is carried out. The effect of surface hardening on the fatigue strength of the lock of the blades of a GTE compressor has been experimentally established.
