Погружение изделий во флюс обеспечивает очистку от пленок оксидов и активирует поверхность, обеспечивая связь между основным металлом и цинковым покрытием. Целью настоящей работы является сравнение пяти модификаций наиболее популярного флюсового состава на основе ZnCl2 и NH4C1 производства ООО «Промхимпермь» с импортным образцом производства Испания, а также выявление влияния модифицирующих компонентов составов на качество оцинковки изделий. Образцы погружали в раствор флюса, подогретого до 50 °С, выдерживали в растворе в течение 15 минут, затем сушили. Исследование структуры и элементного анализа образцов флюсов, высушенных на стальной поверхности, изучали на сканирующем электронном микроскопе TESCAN VEGA SB, равномерность распределения элементов оценивали картированием, проведенным методом энергодисперсионного микроанализа с помощью приставки INCA-act. Для определения смачивающей способности флюсов были проведены измерения краевого угла смачивания по методу «лежащей капли». Смачивание и растекание цинкового расплава по офлюсованной стали оценивали по чистоте отверстий (процинковке) на образцах. Установлено, что все представленные флюсы обладают хорошими смачивающими свойствами. У большинства флюсов выражен «морозный» рисунок кристаллизации хлорида цинка. Все модифицирующие компоненты флюсов (за исключением марганца) распределяются по поверхности равномерно. Визуальная оценка качества цинкового покрытия, формирующегося после флюсования различными составами, показала, что наилучшая процинковка отверстий диаметром 10 мм обеспечивается после флюсов с соотношением основных компонентов: 21 % ZnCl2 – 20 % NH4Cl. Флюс с более полной сорбцией примесей позволил получить чистое подвесное отверстие диаметром 4 мм.</p></abstract><trans-abstract xml:lang="en"><p>The main stage of surface preparation for hot-dip galvanizing is the fluxing operation. Immersing products in flux removes oxide films and activates the surface, providing a bond between the base metal and the zinc coating. The purpose of this work is to compare five modifications of the most popular flux composition based on ZnCl2 and NH4C1 produced by Promkhimperm with an imported sample produced in Spain, as well as to identify the influence of the modifying components of the compositions on the quality of galvanized products. The samples were immersed in a flux solution heated to 50 °C, kept in the solution for 15 minutes, and then dried. The study of the structure and elemental analysis of flux samples dried on a steel surface was studied on a TESCAN VEGA SB scanning electron microscope, with the uniformity of element distribution assessed by mapping carried out by energy-dispersive microanalysis using the INCA-act attachment. To determine the wetting ability of fluxes, contact angle measurements were carried out using the “seated drop” method. The wetting and spreading of zinc melt over fluxed steel was assessed by the cleanliness of the holes (zinc plating) on the samples. It has been established that all presented fluxes have good surface wetting properties. Most fluxes have a frosty crystallization pattern of zinc chloride. All modifying components of fluxes, with the exception of manganese, are distributed evenly over the surface. A visual assessment of the quality of the zinc coating formed after fluxing with various compositions showed that the best galvanization of holes with a diameter of 10 mm is provided after fluxes with the ratio of the main components: 21 % ZnCl2 – 20 % NH4Cl. A flux with more complete sorption of impurities made it possible to obtain a clean hanging hole with a diameter of 4 mm</p></trans-abstract><kwd-group xml:lang="ru"><kwd>горячее цинкование</kwd><kwd>флюсование</kwd><kwd>флюс</kwd><kwd>смачивание</kwd><kwd>растекание</kwd><kwd>краевой угол</kwd><kwd>цинковое покрытие</kwd><kwd>картирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hot-dip galvanizing</kwd><kwd>fluxing</kwd><kwd>flux</kwd><kwd>wetting</kwd><kwd>spreading</kwd><kwd>contact angle</kwd><kwd>zinc coating</kwd><kwd>mapping</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">Знаменский Ю.П.
