| titleOfInvention | Preparation method of strontium-doped tantalum oxide nanorod structure bioactive coating |
| abstract | The invention discloses a preparation process of a strontium-doped tantalum oxide nanorod structure bioactive coating on a tantalum surface, which comprises the steps of firstly, using aqueous solution containing hydrofluoric acid, nitric acid and hydrogen peroxide as hydrothermal solution, carrying out hydrothermal treatment on a tantalum matrix under different hydrothermal conditions, and then carrying out hydrothermal treatment on the obtained tantalum oxide nanorod structure coating again under the strontium-containing hydrothermal environment condition to obtain a coating with a nano-rod-shaped microstructure, wherein the phase of the coating is tantalum pentoxide, the strontium element is doped in the nanorod structure coating, the strontium-doped nanorod structure coating and the matrix have high bonding strength, the obtained coating has small surface roughness, the strontium element is separated out from the coating and shows a rule of first rapid and second slow, bone apatite can be rapidly induced and formed in a body fluid-like environment, and the coating has good bioactivity. |
