Beschreibung
Zusammenfassung:	The invention discloses a method for preparing a medical titanium alloy with a bionic multilayered structure interface. The method comprises the following steps: preparing a hydroxyapatite nanowire through a precursor hydrothermal replacement method, and taking the nanowire as an intercalation material for constructing a simulated natural bone laminar film; and assembling the hydroxyapatite nanowire into a gelatin/chitosan multilayer film by utilizing a layer-by-layer self-assembly technology (a spin-coating method), and thus constructing a film for simulating the natural bone nano layered structure from the bionic angle on the surface of a titanium material. Therefore, the biological function of osteoblast is controlled, and the biocompatibility and bone integration of a titanium alloy transplant are improved.
