Abstract:The kinetic equation of liquid penetration was derived from the suppositions that the solid-liquid interface energy is less than half of the grain boundary energy and the penetration is controlled by the diffusion of solute. The equation, verified by the existed experiment, showed that both thermodynamics and kinetics of liquid penetrating into grain boundary are dependent on solid-liquid interface energy.
Key words: interface; interface energy; wetting; penetration
