Abstract: 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.

Keywords: wetting angle polytherms, wetting threshold, Co - Cr, Ni - Cr, 25X18H9C2 substrates
