In this study, the TiNbTaZr (TNTZ) alloys, which do not contain toxic and allergic elements, have been coated with hard ZrN physical vapor deposition (PVD) coatings to increase their in-vitro corrosion resistance. In-vitro electrochemical behavior of the ZrN coating and uncoated TNTZ alloy was evaluated using open circuit potential (OCP) and potentiodynamic polarization (PDS) techniques, respectively. The characterizations of the coatings were carried out using scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS), and X-ray diffraction (XRD). The SEM examinations showed that ZrN coating is homogeneous. Besides, ZrN coating had a higher corrosion resistance than uncoated TNTZ alloy in Hank's solution.
