Abstract
In model studies of the dispersed solid-liquid-vapor system, thermodynamic functions were found which describe changes in the energy of the system when an isolated pore is filled with liquid. From an analysis of these functions, a class of composite materials was isolated in which there exists the migration pressure which has a physical meaning of suction pressure. In these compositions, the liquid in a pore is acted upon by two opposing forces: capillary pressure and migration pressure. Depending on the ratio of these pressures, the liquid may not fill the pore or may first migrate from the composition into the pore, fill it, and then migrate from the pore into the composition, homogeneous structure being formed in the place of the pore. In compositions which are free from the migration pressure, the liquid fills pores of any size. Pores provide a place for the lakes of liquid. Theoretical conclusions were confirmed by our experiments with WC-Co, WC-Ni, WC-Cu, Cr3C2-Cu, and other composites .
