| Abstract High strength Al-Zn-Mg-Cu alloy type 7010 has been friction stir welded with a standard M10 threaded tool. Microstructure of the joint was investigated in the transverse welding plan where the typical welding zones are clearly recognized. Corrosion performance along these zones was evaluated using the Open Circuit Potential (OCP) and the Electrochemical Impedance (EIS) techniques in a 3.5% NaCl solution at room temperature. Features of sever corrosion as well as localized pitting were observed in both the Heat Affected Zones (HAZ) and the Thermo-mechanically Affected Zones (TMAZ). | ||||
