Electrochemical effects on the fretting corrosion behaviour of Ti6Al4V in 0.9% sodium chloride solution

The extent of wear was profoundly affected by the applied potential, especially for potentials above approximately −0.2 V Ag/AgCl. This effect was related to the increasing oxidation of the third body formed by plastic deformation of the metal found at higher anodic potentials. On the other hand, the mechanical energy necessary for wear was found to be dramatically decreased when anodic potentials are applied.
