Определено влияние режимов обработки на параметры отклика системы глубину и ширину зон лазерной закалки. Показано, что применение поперечных колебаний луча повышает микротвердость, площадь закаленного слоя его равномерность и сохраняет геометрическую форму профиля шлица по сравнению с обработкой дефокусированным пучком. Износостойкость зон упрочненных лазерным лучом значительно выше материала основы.</p></abstract><trans-abstract xml:lang="en"><p>The process of laser hardening of 42KhN2MA steel samples using continuous radiation and transverse beam vibrations at a frequency of 223 Hz has been considered. The influence of processing modes on the response parameters of the system, the depth and width of the laser quenching regions has been determined. It has been shown that the use of transverse beam vibrations increases the microhardness, the area of the hardened layer, its uniformity and preserves the geometric shape of the slot profile compared to processing with a defocused beam. The wear resistance of the laser-hardened regions is significantly higher than the base material.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерное упрочнение</kwd><kwd>износостойкость</kwd><kwd>коэффициент трения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser hardening</kwd><kwd>wear resistance</kwd><kwd>coefficient of friction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Curà F., Mura A. // Mech.
