Индивидуально В-15/41 способен самопроизвольно пассивировать изученные металлы и облагораживать потенциал локальной депассивации в боратном буферном растворе с добавкой 0,01 моль/л NaCl. Наиболее высокими пассивирующими свойствами обладает композиция В-15/41+2-МБТ (9:1), у которой при 8,0 ммоль/л защитный эффект на Ст3 составляет 0,22 В, а на МНЖ5-1 при 4,0 ммоль/л защитный эффект 0,38 В. В 0,01 моль/л водном растворе NaCl при Син=7,0 ммоль/л композиции В-15/41+2-МБТ (9:1) пластины МНЖ5-1 и Ст3 полностью защищены от коррозионного разрушения.</p></abstract><trans-abstract xml:lang="en"><p>The passivation and protective properties of the anti-rust additive V-15/41 and its composition with 2-mercaptobenzothiazole (2-MBT) were studied on metals: St3 low-carbon steel, MNZh5-1 copper alloy in aqueous chloride and borate buffer solutions. Individually, V-15/41 is capable of spontaneously passivating all the metals studied and improving the local depassivation potential in a borate buffer solution supplemented with 0.01 mol/L NaCl. The composition V-15/41+2-MBT (9 : 1) has the highest passivation properties, for which at 8.0 mmol/L the protective effect on St3 is 0.22 V, and on MNZh5-1 at 4.0 mmol/L the protective effect is 0.38 V. In a 0.01 mol/L NaCl solution at 7.0 mmol/L of the composition V-15/41+ 2-MBT (9:1) MNZh5-1 and St3 is completely protected from corrosion destruction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медный сплав МНЖ5-1</kwd><kwd>низкоуглеродистая сталь</kwd><kwd>пассивация</kwd><kwd>защитный эффект</kwd><kwd>степень защиты</kwd><kwd>алкенилянтарная кислота</kwd><kwd>хлоридный раствор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper alloy MNZh5-1</kwd><kwd>low-carbon steel</kwd><kwd>passivation</kwd><kwd>protective effect</kwd><kwd>degree of protection</kwd><kwd>alkenylsuccinic acid</kwd><kwd>chloride solution</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках Госзадания при финансовой поддержке Минобрнауки России «Развитие физико-химических основ процессов коррозии металлов и сплавов и методов их защиты» (регистрационный номер 125012200581-1)</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">G.
