Title:
METHOD FOR DEPOSITING HYDROXYAPATITE ON METAL SURFACE, AND METAL IMPLANT
Document Type and Number:
WIPO Patent Application WO/2021/093690
Kind Code:
A1
Abstract:
A method for depositing hydroxyapatite on a metal surface, and a metal implant. The method for depositing hydroxyapatite on a metal surface comprises: providing a metal substrate; forming a rough structure on the surface of the metal substrate; providing an electrolyte solution; and placing, in the electrolyte solution, the metal substrate having the rough structure formed on the surface thereof, and forming a hydroxyapatite layer on the rough structure by means of electrochemical deposition; raw materials for formulating the electrolyte solution comprise calcium salt, phosphate and hydrogen peroxide. An HA coating with high purity and crystallinity is formed on the surface of a metal implant obtained by the described method, and the HA coating has a relatively strong binding force to the surface of the metal implant, thereby improving the usage safety and reliability of the metal implant.
