В опытах на усовершенствованной экспериментальной установке методом лежащей капли в условиях вакуума установлена температурная зависимость краевых углов смачивания θ(Т) полированной поверхности конструкционной нержавеющей стали 12Х18Н9Т жидким оловом в интервале температур 510–920 К. На политерме θ(Т) изученной системы обнаружена критическая температура смачиваемости, равная около 870 К. По мнению авторов, появление критической температуры в основном обусловлено и связано с началом процессов растворения легирующих элементов стали 12Х18Н9Т в жидком олове.

The temperature dependence of the contact angles θ(Т) of the polished surface of structural stainless steel 12Cr18Ni9Ti with liquid tin in the temperature range 510–920 К was established in experiments on an improved experimental setup using the sessile drop method under vacuum conditions. On the polytherm θ(T) of the studied system, a critical wetting temperature of about 870 K was found. According to the authors, the appearance of the critical temperature is mainly due to and associated with the onset of the processes of dissolution of alloying elements of 12Ch18Ni9Ti steel in liquid tin.
