Surface properties of graphene and graphene/diamond composites located at a substrate with tungsten carbide doped by metals composites

The basis of the obtained materials was 95% (wt%) tungsten carbide with the addition of about 4.75% Co 0.1% Nb and 0.15% Tl. During sintering flake graphene was added and in the case of the second sample also nano diamonds were added into the top layer. Surface properties of the obtained materials were determined by wettability. The apparent surface free energy was described...
