Abstract

Commercially pure titanium (CP-Ti) is extensively used in biomedical applications. However, numerous qualities, including mechanical strength, corrosion resistance, and wear resistance, must be established for long-term performance as an implant material. This study investigates the enhancement of surface properties of CP-Ti through physical vapor deposition (PVD) with ZrN and ta-C (tetrahedral amorphous carbon). Among the coatings, ZrN revealed best overall results, such as adhesion, corrosion, microhardness, and wettability, excluding cell viability when compared to ta-C. E. coli and S. aureus were employed for antibacterial activity and MTS cell viability experiments. Compared to α-titanium, hardness tests revealed 91% increase in ZrN coating, and %22 increase in ta-C coating. Super-hydrophobicity and excellent antibacterial activity were found for ZrN coatings in comparison to ta-C. These findings emphasize the potential of ZrN and ta-C coatings to improve the surface properties of titanium, encouraging it to be used in biomedical devices.

生物医学用途的钛上ZrN和ta-C涂层:改善附着力、腐蚀、抗菌活性和细胞毒性

商业纯钛(CP-Ti)广泛应用于生物医学领域。然而，许多品质，包括机械强度，耐腐蚀性和耐磨性，必须建立作为植入材料的长期性能。本文研究了ZrN和ta-C(四面体非晶碳)的物理气相沉积(PVD)对CP-Ti表面性能的增强。与ta-C涂层相比，ZrN涂层在附着力、腐蚀性、显微硬度和润湿性等方面的总体效果最好，但不包括电池活力。采用大肠杆菌和金黄色葡萄球菌进行抑菌活性和MTS细胞活力实验。与α-钛相比，ZrN涂层硬度提高91%，ta-C涂层硬度提高%22。与ta-C相比，ZrN涂层具有超疏水性和优异的抗菌活性。这些发现强调了ZrN和ta-C涂层改善钛表面性能的潜力，鼓励其用于生物医学设备。
