▎ 摘　　要

NOVELTY - Multifunction titanium alloy coating comprises two-dimensional material, antibacterial and titanium and alloy. The two-dimensional material is graphene and the antibacterial is berberine. The multifunction of the titanium alloy is beryllium-gadolinium-titanium . USE - The multifunction titanium alloy coating is used for preparing materials for promoting osteogenic differentiation of MC3T3-E1 cells and antibacterial materials and field of artificial joints (all claimed). ADVANTAGE - The multifunction titanium alloy coating has excellent anti-bacterial effect, strong practicability and wide application prospect, and exhibits higher expression of osteogenic related gene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of a multifunction of a titanium alloy.
