In this study, Ti_3.6Nb_1.0Ta_0.2Zr_0.2 based coatings were deposited on anodized and non-anodized aluminum surfaces by PVD. For this purpose, a target for the magnetron sputtering PVD system was prepared from a β-type Ti–29Nb–13Ta–4.6Zr bulk alloy via hot-forgings. Surface morphologies and elemental composition analysis of the TNTZ-based PVD coatings were conducted using scanning electron microscopy attached with an energy dispersive spectroscopy incorporated (SEM-EDS). A micro-scratch and hardness tester was used to evaluate the adhesion and mechanical properties of the deposited coatings. The contact angle and electrochemical corrosion measurements were applied to assign the wettability levels and potential usability of the coated surfaces under in-vitro conditions. Also, the corrosion resistance of the coatings was compared with commercial Ti and Ti6Al4V alloys. The results showed that the coated surfaces were exhibited a hydrophilic behavior and adequate in-vitro resistance in simulated body fluids (SBF). Besides, the TNTZ coatings on anodized surfaces were presented different cracking mechanisms and higher adhesion resistance than that of their non-anodized surfaces. The reason for the behavior has been discussed in the present study.

在本研究中，Ti _3.6 Nb _1.0 Ta _0.2 Zr _0.2基涂层通过 PVD ​​沉积在阳极氧化和非阳极氧化的铝表面上。为此，磁控溅射 PVD ​​系统的靶材是通过热锻由 β 型 Ti-29Nb-13Ta-4.6Zr 块状合金制备的。TNTZ 基 PVD ​​涂层的表面形貌和元素组成分析是使用扫描电子显微镜进行的，该显微镜结合了能量色散光谱 (SEM-EDS)。使用微划痕和硬度测试仪来评估沉积涂层的附着力和机械性能。接触角和电化学腐蚀测量用于确定体外条件下涂层表面的润湿性水平和潜在可用性。此外，涂层的耐腐蚀性能与商用 Ti 和 Ti6Al4V 合金进行比较。结果表明，涂​​层表面在模拟体液（SBF）中表现出亲水性和足够的体外抗性。此外，阳极氧化表面上的 TNTZ 涂层呈现出不同的开裂机制和比非阳极氧化表面更高的抗粘附性。本研究已经讨论了这种行为的原因。
