Oxide is not a substance, it is a chemical state. So you have to ask "Oxide of what?" Oxide of hydrogen is water. Oxide of silicon is glass. You can strike a match on wet glass. So you just need to figure out what you are talking about.
Oxide films formed on the surface of metal helps in reducing coefficient of friction of the metal. I am wondering if the same theory applies to metal surface. Titanium dioxide is a good photocatalyst and so it can generate a layer of oxide film on its surface. If I were to add titanium dioxide layer in tetrahedral-amorphous carbon (ta-C) coating (non-metallic), can the coefficient of friction be reduced? Is the theory of oxide film on metal applies to that of non-metal?
