外文摘要：Additive manufacturing has revolutionized implantology by enabling the fabrication of customized,highly porous implants.Surface modifications using electrochemical methods can significantly enhance the bioactivity and bio-compatibility of biomaterials,including 3D-printed implants.This study investigates novel coatings on 3D tita-nium(Ti)samples.Mesh Ti samples were designed and subjected to plasma electrolytic oxidation(PEO)to form a calcium phosphate coating.Subsequently,a layer of polydopamine(PDA)was applied.The electrochemical prop-erties and morphology of the coatings were analyzed.Scanning electron microscopy(SEM)and energy-dispersive X-ray spectroscopy(EDS)revealed well-developed coatings containing calcium phosphates(including hydroxya-patite),titanium dioxide,and polymerized dopamine,suggesting promising bioactive potential.Composite layers incorporating PDA exhibited superior protective properties compared to base PEO coatings.
