The polytherms of density, surface tension of the Cu-Al system melts and wetting angles of Ni-Cr, Co-Cr substrates, 25X18H9C2 stainless steel and titanium were studied by the sessile drop method. The drop contour was processed by dint of current information technologies, in particular, using the ImageJ software package [1]. The equations of density polytherms and surface tension of the Cu-Al system melts were established. It was shown that Cu-Al melts wet the substrates at 1000 K and more. We revealed the features of temperature dependences of the wetting angles.

Density and surface tension for Sn1-xNix(x = 0; 0,05; 0,1) have been measured by means of sessile drop method. Temperature dependences of these parameters as well as influence of Ni-atoms on density and surface tension were analyzed. It is shown that chemical ordering is one of the most important factor, determining surface properties and density.

We chose two glass compositions suitable for the synthesis of foam glass. The influence of additive at the amorphous silica charge in the amount of 20% and 100%, a by-product in the leaching of serpentinite, was studied. By the method of stable temperature drop, the crystallization ability of the welded glass compositions was studied. The surface tension was measured by the sessile drop method.

Yttria Partially Stabilized Zirconia

The wetting behavior of molten Cu-Ti alloys with titanium content of 10mass%, 20mass% and 30mass% on the Yttria Partially-Stabilized Zirconia (Y-PSZ) substrates was investigated at 1273K using the sessile drop method. The wettability improved with increasing the titanium content of the alloy. The stabilized contact angles of Cu-10mass%Ti, Cu-20mass%Ti and Cu-30mass%Ti alloys on the Y-PSZ substrate were measured to be 69°, 47°and 30°, respectively. The surface tension of the molten Cu-Ti alloys and the work of adhesion of alloy/substrate interface increased with increasing the titanium content. A larger work of adhesion attributes to firmer bonding between the molten Cu-Ti alloy and the Y-PSZ substrate, and can greatly improve the wettability.

Abstract The study involved measurements of surface tension of liquid binary copper-bismuth alloys with respect to their chemical composition and temperature as well as investigations of the liquid alloy - refractory material - gaseous phase system wettability using usual refractory materials, i.e. aluminium oxide, magnesium oxide and graphite. The experiments were performed with the use of sessile drop method and a high-temperature microscope coupled with a camera and a computer was utilised.
