Bonding effect of liquid magnesium with open-celled carbon foam in interpenetrating phase composite

The issue of bonding formation in liquid metal/open-celled carbon foam (Cof) systems was examined, taking into account the practical aspects of the synthesis of a new type of Mg-C metal material composite. The problem is complex due to the strong oxidation and intense evaporation of liquid magnesium, as well as the 3D geometry of the carbon component, where metal transport occurred through the foam cells’ windows. Laboratory experiments performed at 700°C in ceramic crucibles showed that spontaneous carbon foam infiltration by liquid metal is impossible under the applied conditions, either in an air atmosphere coupled with flux protection or under argon protection.
