Важную роль в эффективности смазки играет поверхностное натяжение масла на границе раздела фаз. Определение свойств поверхностного натяжения моторных масел очень желательно, так как это имеет прямое промышленное значение. Хотя поверхностное натяжение не является самым важным свойством в определении относительной смазывающей способности, связь между физическими свойствами отработанных масел и поверхностным натяжением исследована в настоящее время недостаточно. Различия в поверхностном натяжении смазочных масел вызовут различия в способности поддержания этих тонких пленок. Представляется, что в отсутствие опубликованных данных о поверхностном натяжении отработанных моторных масел исследование температурных зависимостей будет иметь значение для решения задач диагностики. В статье основное внимание уделяется измерению межфазного натяжения и его значению при загрязнении масла, например, полярными органическими соединениями, которые образуются при работе двигателя. Взаимодействие масла, воды и кислорода снижает функциональность масла. Эти загрязнения притягиваются к границе раздела «масло/воздух» и в результате значительно уменьшают межфазное натяжение. Измерены и аппроксимированы температурные зависимости плотности и коэффициентов поверхностного натяжения свежих и отработанных судовых моторных масел. Установлены корреляции между этими параметрами, что является важным для задачи диагностирования.</p></abstract><trans-abstract xml:lang="en"><p>It is well known that the effectiveness of lubricating oils depends on temperature. An important role in the effectiveness of lubrication is played by the sur-face tension of the oil at the interface of phase. Determination of the surface tension properties of motor oils is very desirable, since it has direct industrial significance. Although surface tension is not the most important property in determining relative lubricity, the relationship between the physical properties of used oils and surface tension has not been sufficiently studied to date. Differences in the surface tension of lubricants result in differences in their ability to maintain these thin films. It seems that in the absence of published data on the surface tension of used motor oils, the study of temperature dependences will be important for solving diagnostic problems. This article focuses on the measurement of interfacial tension and its significance when the oil is contaminated, for example, by polar organic compounds that are formed during engine operation. Interaction of oil, water and oxygen reduces oil functionality. These contaminants are attracted to the oil/air interface and, as a result, significantly reduce the interfacial tension. The temperature dependences of the density and surface tension coefficients of fresh and used marine motor oils have been measured and approximated. Correlations between these parameters have been established, which is important for the diagnostic task.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>судовые моторные масла</kwd><kwd>коэффициент поверхностного натяжения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>marine engine oils</kwd><kwd>surface tension coefficient</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках госзадания Федерального агентства по рыболовству, рег. № 122030900056-4.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the state assignment of the Federal Fisheries Agency, reg.
