High-temperature wetting and interfacial interaction in AlB12-Al system

The article is dedicated to the study of wetting and specifics of interaction between phases on the drop-substrate interface in the AlB12-Al system. Contact angles between an aluminum melt and an aluminum dodecaboride ceramic substrate were studied using the sessile drop method. It was found that upon aluminum melting at 660°C, contact angles are Θ >> 90 deg. Intensive spreading of the aluminum melt starts at 1200°C with contact angles Θ ≈ 15 deg. The X-ray spectral microanalysis showed that AlB12 grains recrystallized through the aluminum melt on the interface. In addition, due to the absence of active chemical interaction, the AlB12-Al system can be recommended for the development of new composite materials.
