NOVELTY - Nano-composite material comprises 80-90 wt.% nano-oxide particles comprising ferric oxide (preferred), titanium oxide, titanium dioxide and/or aluminum trioxide as an anti-wear component and 10-20 wt.% multilayer graphene as a antifriction component, where the nano-oxide particle and the multilayer graphene are prepared by adopting a liquid phase peeling method involving dispersing the nano-oxide particle evenly on the surface and interlayer of the graphene sheet. The nano-oxide particles have a particle size of 30-300 nm. The ferric oxide particle is in the shape of sphere or spindle. When other oxide particles in the nano-oxide particles except iron trioxide are present, then the anti-wear components are calculated according to any mass ratio. USE - The material is useful in titanium alloy surface. ADVANTAGE - The material improves anti-wear and antifriction properties on surface of titanium alloy even under severe condition such as high load, and has strong stability of friction layer compared to existing material.
