Abstract
This study used a combination of laser remelting (LR) and micro-arc oxidation (MAO) treatment techniques to surface-modify TC4 alloy for implant applications. The LR-MAO coatings successfully maintained the porous structure of MAO while endowing the coatings with a microgroove structure and improving the roughness of the composite coatings. The surface morphology, physicochemical, and biological properties of the LR-MAO composite coatings were systematically investigated. The results showed that LR pretreatment is an effective method to enhance the biocompatibility of the MAO implant surface.
