   <abstract xml:lang="ru">
    <p>В работе представлены результаты исследований по определению размеров зон термоупрочнения прямоугольным пятном полупроводникового лазера, микротвердости и триботехнических свойств образцов стали 55. Испытания на трение и износ были выполнены при трении скольжении и трении качении. В качестве эталонов были выбраны образцы цементованной стали 18ХГТ. Установлено, что глубина зон лазерной закалки и микротвердость при удельной энергии излучения 9 и 6 Дж/мм2 составила 1,53 и 0,97 мм, 9000-11000 и 7000-7600 МПа соответственно. Минимальные моменты трения при скольжении стального контртела от удельной нагрузки получены для образцов после лазерного термоупрочнения при большей удельной энергии излучения. Глубина треков износа при качении шариков из стали ШХ15 для образцов стали 55 термоупрочненных при большей удельной энергии излучения была в 1,5 раза меньше, чем у цементованных образцов из стали 18ХГТ.</p>

    <p>The paper presents the results of studies on determining the size of heat-hardening zones with a rectangular spot of a semiconductor laser, microhardness and tribotechnical properties of 55 steel samples. Friction and wear tests were performed for sliding and rolling friction. Samples of 18HGT cemented steel were used as reference materials. It is found that the depth of the laser quenching zone and the microhardness at specific radiation energies of 9 and 6 joule/mm2 is 1.53 and 0.97 mm, 9000-11000 and 7000-7600 MPa, respectively. The minimum moments of friction during sliding of the steel counterbody from the specific load were obtained for samples after laser thermal hardening at a higher specific radiation energy. The depth of wear tracks during rolling of balls made of SHH15 steel for steel samples 55 thermally-hardened with a higher specific energy of radiation was 1.5 times less than that of cemented samples made of 18HGT steel.</p>
