Покрытие синтезировали путем лазерного спекания порошковой смеси на поверхности низкоуглеродистой нелегированной стали. В результате лазерной обработки на поверхности металла образуется оксидно-керамический слой, который обладает антифрикционными свойствами и высокой твердостью. Исследован фазовый состав и рельеф поверхности полученного композита. Установлено снижение коррозионной стойкости полученного композита в условиях электрохимической коррозии в среде нейтрального буферного раствора по сравнению с необработанной сталью. Для повышения коррозионной стойкости был применен метод ингибиторной обработки. В качестве ингибиторов применялись следующие композиции: октановая кислота, октановая кислота–гексаметилентетрамин, октановая кислота–гидразин-гидрат и октановая кислота–2,4-динитрофенилгидразин. Ингибиторы наносились методами пропитки с последующим нагревом образцов до 120°C. Все исследованные смесевые ингибиторы повысили коррозионную стойкость материала к электрохимической коррозии в нейтральном боратном буферном растворе.</p></abstract><trans-abstract xml:lang="en"><p>The effect of mixed inhibitors based on octanoic acid and nitrogen compounds with a negative degree of oxidation on the corrosion properties of a ceramic oxide coating of the composition B4C–BN–Bi2O3–MnO2 has been studied. The coating was synthesized by laser sintering of a powder mixture on the surface of low-carbon non-alloy steel. As a result of laser treatment, an oxide-ceramic layer is formed on the metal surface, which has antifriction properties and high hardness. The phase composition and surface relief of the resulting composite are investigated. A decrease in the corrosion resistance of the resulting composite under conditions of electrochemical corrosion in a neutral buffer solution medium compared with untreated steel has been established. To increase the corrosion resistance, an inhibitory treatment method was applied. The following compositions were used as inhibitors: octanoic acid, octanoic acid–hexamethylenetetramine, octanoic acid– hydrazine hydrate and octanoic acid-2,4-dinitrophenylhydrazine. The inhibitors were applied by impregnation methods followed by heating of the samples to 120°C. All the studied compound inhibitors increased the corrosion resistance of the material to electrochemical corrosion in a neutral borate buffer solution.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксидно-керамическое покрытие</kwd><kwd>карбид бора</kwd><kwd>оксид висмута (III)</kwd><kwd>оксид марганца (IV)</kwd><kwd>антикоррозионные свойства</kwd><kwd>ингибиторная обработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxide-ceramic coating</kwd><kwd>boron carbide</kwd><kwd>bismuth (III) oxide</kwd><kwd>manganese (IV) oxide</kwd><kwd>anticorrosive properties</kwd><kwd>inhibitory treatment</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы выражают благодарность Российскому научному фонду за финансовую поддержку (проект №19-79-20012).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">S.M.
