TLDR
In this article, the authors proposed a preparation method for medical titanium with a trace element slow-release function or a titanium alloy implant material as well as an application of the medical titanium.Abstract:
The invention relates to medical titanium with a trace element slow-release function or a titanium alloy implant material as well as a preparation method and an application of the medical titanium. The invention adopts the technical scheme that the preparation method comprises the following steps: putting a polished titanium-containing metal sheet into an electrolyte as an anode for anodic oxidation; flushing and drying the titanium-containing metal sheet subjected to anodic oxidation, carrying out heat treatment for 1-3 hours at a temperature of 100-500 DEG C, naturally cooling and ultrasonically cleaning and drying; and putting the dried titanium-containing metal sheet into one of or mixed solution of more than any two strontium hydroxide, strontium acetate, zinc acetate or magnesium acetate, carrying out hydrothermal reaction for 0.5-12 hours in a closed container at a temperature of 100-300 DEG C, naturally cooling, taking out, cleaning and drying, and carrying out heat treatment for 1-3 hours at a temperature of 450-550 DEG C to obtain the medical titanium with the trace element slow-release function or the titanium alloy implant material. The medical titanium or the titanium alloy implant material as well as the preparation method and the application thereof have the beneficial effects that the preparation method is simple and reliable, the loading quantity and the release amount of trace elements of the medical titanium in a nano tube are controllable, the medical titanium and the biological activity on the alloy surface can be better promoted, and the application prospect is good in the medical implant material.read more
