Enhanced physicochemical and biological properties of C/Cu dual ions implanted medical titanium

Enhanced physicochemical and biological properties of C/Cu dual ions implanted medical titanium

It is increasingly popular for titanium and its alloys to be utilized as the medical implants. However, their bio-inert nature and lack of antibacterial ability limit their applications. In this work, by utilizing plasma immersion ion implantation and deposition (PIII&D) technology, the titanium...
