Аннотация


В последние годы со стороны исследователей возрос интерес к управлению смачиваемостью металлических поверхностей различными жидкостями в связи с широким спектром областей применения.
В частности, применение гидрофобных функциональных поверхностей в теплоэнергетических установках и системах способствует повышению их эффективности и надежности. Несмотря на огромное количество существующих способов гидрофобизации металлических поверхностей, мировым научным сообществом был предложен и интенсивно развивается способ, основанный на текстурировании микро-/ наномасштабного рельефа с использованием лазерного оборудования (лазерная абляция). В данной работе было проведено исследование по определению влияния модификации латунных поверхностей с использованием лазерного оборудования на геометрические параметры текстурируемого рельефа и свойства смачиваемости, на основе результатов которого была предложена математическая модель прогнозирования смачиваемости.


Ключевые слова
