Abstract
One way to increase the biocompatibility of the surface of titanium alloys is to produce a surface layer with better physicochemical properties of the whole set than the base. The most popular methods of surface modification used in medical products include: chemical methods (eg. sol-gel method, atomic layer deposition (ALD)) and electrochemical (eg. anodic oxidation, fluorescent processing). Therefore, authors of this paper carried out a comparative analysis of \(TiO_{2}\) layers produced both using chemical (ALD) and electrochemical (anodic oxidation) methods. The study was performed based on evaluation of electrochemical properties of produced TiO2 layer on the Ti6Al7Nb substrate alloy. As a part of electrochemical properties testing, potentiodynamic, potentiostatic and impedance studies were performed. All the tests were carried out in simulated physiological Ringer’s solution in T = \(37\pm 1^{\circ }C\) temperature. Based on the results it was found that the most favorable set of electrochemical properties characterises \(TiO_{2}\) layer deposited by ALD method.
