▎ 摘　　要

NOVELTY - Graphene/carbide synergistically enhanced magnesium-based nanocomposite bone implant comprises magnesium alloy bone implant matrix, where nanometer graphene and the in situ generated nano titanium-carbon (TiC) ceramic phase are dispersed inside the matrix. USE - Graphene/carbide synergistically enhanced magnesium-based nanocomposite bone implant. ADVANTAGE - The graphene/carbide synergistically enhanced magnesium-based nanocomposite bone implant has remarkably improved laser forming performance, corrosion resistance of the magnesium-based nanocomposite bone implant is significantly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for forming graphene/carbide synergistically enhanced magnesium-based nanocomposite bone implant, which involves: (A) depositing nano metal titanium on the surface of nanoscale graphene by unbalanced magnetron sputtering process; (B) weighing medical spherical magnesium alloy powder and graphene modified by nano titanium, using a ball-free ball milling process assisted by inert gas to obtain a uniformly mixed composite powder; and (C) forming composite material powder under the protection of high purity argon gas by laser selective melting process to obtain in-situ synthesized nano-TiC ceramics and nano-graphene synergistically enhanced magnesium-based nanocomposite bone implants.
