Abstract

The dependence of the wetting angle of pure Zn (99.9%) and Zn-Mo-Al-Mg (Serbian bronze) of compressed Co-W powder on the temperature in an atmosphere of pure He (grade A) was studied using the large "lying" drop. Wetting angle was measured in the CorelDraw x12 software environment. Found: 1) With an increase in temperature, the wetting angle decreases slightly. This is because the melt drop does not spread over the surface of the substrate but is impregnated into the substrate; 2) Zn additives reduce the wetting angle. A repeated study of the wetting angle of the samples showed that in the case of pure zinc, the results of the two experiments are in good agreement, and in the case of the "Serbian bronze" the results differ by 9 degrees, which is associated with the concentration and porosity of the substrate.
