Abstract

The polytherms of density, the surface tension of melts of the Cu–Al system and wetting angles of Ni–Cr, Co–Cr, 25Cr18N9C2 stainless steel and titanium substrates are studied using the lying drop method. The drop contour is processed using modern information technologies, in particular, using the ImageJ software package. Equations for the polytherms of density and surface tension of the melts of the Cu–Al system are obtained. The Cu–Al melts are shown to wet the substrates at 1000 K or more. The features of the temperature dependences of the wetting angles are revealed.
