Purpose: Characterization of the electrochemical behavior of anodized implant rods made of the titanium alloy Ti6Al4V ELI after immersion in air-saturated Ringer's solution was presented in the paper. Design/methodology/approach: The anodized and deformed by bending at angle 20° specimens (dia 6 mm) were characterized electrochemically in two zones: the max tensile (I) and the max. compressive stress (II). Impedance spectra (EIS) and corrosion potential measurements were performed on 1, 6, 10 and 16th day after immersion in Ringer's solution. Findings: Bending caused an apparent decrease of the protective properties of the anodic layer, but the characteristic two-layer anodic film and the values of corrosion potentials were restored due to immersion in Ringer's solution. The regions of the compressive stresses show much stronger tendency to regenerate surface properties. Research limitations/implications: The electrochemical tests in Ringer's solution performed only in static conditions will be followed by fatigue tests in SBF. Practical implications: Results of the work are of great importance for surgical practice in the pre-operative stage of spinal surgery procedures. The explanation of the observed phenomena is proposed. Originality/value: Different stress zones formed on implant alloy during bending were described electrochemically. Results of studies evidenced that changes in the electrochemical behaviour in vitro in Ringer's solution are advantageous with regard to the protective properties of the investigated alloy.
