摘要

The contact heating sessile drop method was applied for a fundamental study concerning the wettability and reactivity of liquid Si-16.2at.%Ti (eutectic composition) in contact with glassy carbon. The evolution of the contact angle behaviors and spreading kinetics were evaluated at three different temperatures. A strong temperature dependence was found by analyzing the spreading kinetics in determining the achievement of the equilibrium at the interface. Different spreading stages with different slopes depend on whether the diffusion of reacting phases (liquid Si and C) through the growing reaction layer (SiC) starts to be the rate-limiting factor. On the contrary, the final contact angle value seems not affected by the temperature. The solidified Si-Ti eutectics/GC samples were examined both at the top of the drop and at the cross section by SEM/EDS. The presence of C pockets of dissolution and a SiC layer at the interface confirmed the reactive nature of the interaction mechanisms. In addition, a thicker layer of SiC at the triple line was detected and most probably responsible for pinning the alloy drop at a measuredfinal value of contact angle of 43 degrees +/- 2.
