US 2021/0079532 A1 · METHOD FOR COATING ON SURFACE OF MEDICAL PEEK MATERIAL, TITANIUM HAVING MICROPOROUS STRUCTURE

Abstract

In a method for coating on a surface of a medical PEEK material with titanium to have a microporous structure, titanium is coated on a surface of polyether ether ketone (PEEK) via magnetron sputtering. The surface of the titanium coated on the surface of PEEK is polished via an electromagnetic polishing apparatus. A thin-film with titanium dioxide (TiO2) having a microporous structure is formed on the polished surface of the titanium via an anodic oxidation treatment.
