Установлено, что на поверхности меди М1наблюдается упрочняющий диффузионный слой толщиной до 1,5 мм, а сплава МН2,5КоКрХ – 0,6 – 1,4 мм, что объясняется сдерживанием диффузионного процесса содержащимися в нем легирующими элементами с последующей термической обработкой. В качестве основных показателей работоспособности диффузионного слоя использовали его толщину и микротвердость. При проведении анализа исследованных образцов с покрытием установлена целесообразность нанесения на рабочие узкие стенки кристаллизатора алюминиевого газотермического покрытия с последующей термической обработкой в защитной среде по скорректированным режимам и испытание кристаллизатора на МНЛЗ с оценкой состояния стенок в процессе эксплуатации и изменения качества разливаемого металла.</p></abstract><trans-abstract xml:lang="en"><p>To increase the service life of molds of CCM, there were createddiffusion layers on their worked narrow sides of copper M1 andcopper alloy MN2.5KoKrKh by sputtering of aluminum layer about1.5 mm with subsequent diffusion annealing at T = 800 °C during10 hours in an oxidizing atmosphere. It was found that on the copper surface of M1 it was observed hardening diffusion layer with thickness up to 1.5 mm, and of alloy MN2.5KoKrKh – 0.6 to 1.4 mm, that can be explained by the deterrence of diffusion process of contained alloying elements at subsequent thermal treatment. As the main indicators of the health of the diffusion layer authors used its thickness and microhardness. Du ring the analysis of the coated samples the feasibility of the application working on the narrow wall of the mold with aluminum thermal spray coating was established, followed by heat treatment in a protective atmosphere adjusted modes. The authors tested the mold of continuous casting machine with the assessment of the condition of the walls in the process of operation and changes in the quality of cast metal.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кристаллизатор МНЛЗ</kwd><kwd>узкая стенка</kwd><kwd>газотермическое покрытие</kwd><kwd>термообработка</kwd><kwd>диффузионный слой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mold</kwd><kwd>narrow wall</kwd><kwd>thermal spray coating</kwd><kwd>heat treatment</kwd><kwd>diffusion layer</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">Novikov I.I.
