Abstract
This study fabricated three biomimetic structures (cicada wing, shark skin, and moth eye) on TA1 titanium with wire electrical discharge machining (WEDM) and coated them with ZrN. ZrN coating increased static contact angles, which reduced microbial adhesion. The moth-eye structure showed the highest contact angle (136.94 ° ± 1.1 °), achieving 99.0 % antibacterial rate, which outperformed unstructured pure titanium with ZrN (39.52 %). The TA1-Moth-Eye-ZrN structure improved antibacterial performance and corrosion resistance, demonstrating good biocompatibility and potential applications in orthodontic treatment.
