The paper analyzes traditional methods of hardening. The results of comparative wear tests of the samples made of 20KhNZA steel after nitrocementation and electromechanical surface quenching are presented. The results of the wear tests of the samples made of steel 20KHN3A after nitrocementation and electromechanical surface quenching indicate the high efficiency of the electromechanical processing technology. A competitive feature of the technology of electromechanical surface quenching of parts made of 20KHNZA steel is the possibility of flexible control of the parameters of high-speed electric heating and simultaneous thermoplastic deformation of the material of the surface layer of the most loaded parts in order to form gradient fast-quenched structures at a depth of up to 0.05…0.1 mm in the manufacture and repair of parts. Conclusions and recommendations on the method of using these types of hardening are providedю English version of the article is available at URL: https://panor.ru/articles/increasing-the-equipment-service-life-by-electromechanical-surface-quenching/64911.html |
