Reactive wetting in liquid Cu alloy – carbon and silicon carbide systems

Wettability of carbon and SiC by liquid Cu – Si alloys was measured by the sessile drop method and was mainly investigated from a thermo-dynamical view point. Penetration phenomena of liquid Cu – Si alloy into porous carbon was also investigated. It was found that it is possible to expect whether wetting system or non-wetting system from thermo-dynamic calculation.
