Abstract

Wettability of Al on Cu coated graphites and the interfacial reactions between Al and the Cu coating were analyzed to examine in depth the effect of the Cu coating layer used to enhance the wettability of Al on carbon. The wetting behaviors of Al according to Cu coating method and Cu thickness were also investigated. The Cu/Cu double layer coated by sputtering the Cu single layer coated by electroless plating because it improved the stability of the Cu layer coated on graphite at high temperature. In order to suppress the dewetting of Al on graphite and improve the wettability of Al on graphite, a thick Cu coating layer to supply sufficient Cu atoms for saturation in an Al droplet is needed.
