The temperature dependence of the contact angle of wetting allows of Pb-Na of different concentrations on substrates of Co-Cr, Ni-Cr and stainless steel substrate 25X18H9C2 was studied by the method of a lying drop. Measurements were carried out by the method of a lying drop from 359°C 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.
