Banakh (c) Keywords: Titanium; Anodic oxidation; Ellipsometry Abstract: The long-time behaviour of CP titanium in 1 M H.sub.2SO.sub.4 has been investigated. The authors revealed electrochemical behaviour during the long-time chrono-amperometric experiments. The ex-situ observations (EIS, ellipsometry, SEM and optical microscopy) brought out information concerning morphological changes of the surface as well as the change in the oxide thickness during the anodic oxidation process. From the obtained data, the authors developed a hypothesis describing the potentiostatic anodisation of titanium at voltages (up to 15 V) in 1 M H.sub.2SO.sub.4 with respect to time of anodisation.
