Abstract
The case of samples of point frogs from austenitic steel 110G13MLS was used to demonstrate the possibility of strengthening the surfaces of wear-resistant steels by jet electrohydraulic-pulsed treatment. It is determined that 1.4 times increase of hardness of the surface of a steel sample is caused by microplastic deformation of the sliding and twinning type developing in it. This results in increase of wear-resistance of the steel surface layer.
