Методом лежащей капли изучена температурная зависимость краевого угла смачивания сплавов Pb - Na разной концентрации на подложках из Co - Cr, Ni - Cr, нержавеющей стали 251892. Измерения проводились методом лежащей капли в широком интервале температур от 359°С до 800 °С в атмосфере чистого  марки А. Показано, что значение угла смачивания уменьшается с увеличением температуры, наблюдаются пороги смачивания. The temperature dependence of the contact angle for Pb - Na melts of different concentrations on Co - Cr , Ni - Cr and stainless steel 25X18H9C2 substrate was studied by the method of a lying drop. Measurements were carried out by a lying drop method in the temperature range from 359 to 800 °C in an atmosphere of pure helium grade A. It is shown that the value of the wetting angle decreases with increasing temperature, wetting thresholds are observed.
