Beschreibung
Zusammenfassung:	The invention discloses a method for improving biological activity of titanium alloy bone, which comprises the following operation steps: soaking and cleaning the surface of titanium alloy by adopting an alkaline solution, sequentially spraying and washing by adopting alcohol, acetone and clear water, and drying in a vacuum environment; the titanium alloy is rapidly placed in an atomization box, pitting corrosion is conducted on the surface of the titanium alloy through acid mist, and blow-drying is conducted after pitting corrosion is completed; the method comprises the following steps: immersing a titanium alloy into a collagen solution, taking out the titanium alloy, uniformly spraying metal powder to the surface of the titanium alloy in a vacuum environment before the collagen solution is completely dried, immersing the titanium alloy into the collagen solution containing gelatin sustained-release balls, taking out the titanium alloy, and blow-drying the titanium alloy by adopting nitrogen in a nitrogen e
