In this study, the change of porosity and roughness of carbon nanostructures, including fullerenes, carbon nanotubes and graphene was investigated according to oxidation process. The effect of oxidation was more sensible on smoother surface of nanostructures. Oxidation increases surface roughness of graphene up to 5.2% and porosity up to 35.2%. While, roughness of hummers graphene is 13....

Plasma Surface Metallurgy /Alloying is a kind of surface metallurgy/alloying to employ low temperature plasma produced by glow discharge diffuse alloying elements into the substrate material form an alloy layer. It different with ion nitriding technology, which only applicable infiltration non-metallic elements. “Double Glow Technology”, also known as “Xu-Tec Process” can utilize any chemical i...
