摘要

在TA1钛合金上采用线切割加工（WEDM）制备了蝉翅、鲨鱼皮和蛾眼三种仿生结构，并在其表面涂覆了ZrN。ZrN涂层增加了静态接触角，减少了微生物的粘附。蛾眼结构的接触角最高（136.94°±1.1°），抗菌率达到99.0%，优于非结构纯钛（39.52%）。TA1-Moth-Eye-ZrN结构提高了抗菌性能和耐腐蚀性，具有良好的生物相容性，在正畸治疗中具有潜在的应用前景。

Biomimetic structures in orthodontic brackets: a strategy for enhanced antibacterial performance and corrosion resistance

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.
