Abstract

During liquid phase sintering, WC-Co composite forms a typical solid-liquid two-phase system where the solid particles of WC are immersed in liquid Co. Liquid Co tends to migrate from the regions with bigger WC particles and/or higher liquid Co volume fraction to the region with smaller WC particles and/or lower liquid Co volume fraction, thus causing the redistribution of Co within WC-Co composite, which phenomenon is called as liquid phase migration. The kinetics of liquid phase migration is of great practical importance for the liquid phase sintering of functionally graded WC-Co composite materials. This paper describes a numerical simulation study on the kinetic process of liquid phase migration, demonstrating how Co gradients in WC-Co composite change with time under various conditions.
