Abstract
Mathematical modeling of infiltration dynamics of liquid Cu-Si alloy into porous carbon is presented. Two-dimensional infiltration equations are developed using the Washburn equation in the limit of both interface and diffusion control, for situations where the capillary radius decreases either linear or parabolic, and the contact angles are assumed to exponentially decrease with time during infiltration. One major manufacturing process for the Cu-Si/C composites is liquid melt infiltration. This article focuses on nonequilibrium wetting effects and offers a fundamental approach to these complex kinetic phenomena.
