To characterize mechanically induced surface damage scratch and rotating bending tests were performed on the implant alloy TiAl6Nb7 with different surface conditions (polished, thermally oxidized, anodically oxidized) in Hank's solution and in newborn calf serum at 37°C. The surface processes taking place during repassivation or due to the fatigue loading were identified by measuring the free corrosion current and potential. Light and scanning electron microscopic investigations were used to correlate surface changes with the results of the electrochemical measurements.
