Abstract
In order to achieve both antibacterial and biological activity on the SLA (sandblasted large-grit acid-etched) surface, this study utilized alkali treatment and magnetron sputtering to create a layer of AT + Ta (alkali treatment and tantalum) composite coating on the SLA surface to enhance biocompatibility and antibacterial properties. The AT + Ta coating successfully maintained the hierarchical porous structure of alkali treatment while also improving antibacterial properties. The physical and chemical properties, antibacterial properties, and biocompatibility of the AT + Ta coating were systematically investigated. The results suggest that AT + Ta coating could be an effective approach for enhancing the surface properties of SLA implant.
