| Abstract | -Friction stir welding (FSW) is a promising solid state joining process and is widely being considered for Al-alloys especially for joining aerospace and aircraft aluminum alloys. In this work, the microstructure and corrosion behavior of the FSW 2024-T3 Al-alloy are studied. The friction stir welding was carried out by using CNC milling machine at different tool rotational speeds and welding speeds. The microstructure of weld or stir nugget (SN), thermo-mechanically affected zone (TMAZ), heated affected zone (HAZ) and base metal were observed by optical microscopy. The corrosion tests of base alloy and welded joints were carried out in 3.5%NaCl solution at a temperature of 30°C. Corrosion current and potential were determined using potentiostatic polarization measurements. It was found that the corrosion rates of welded joints were higher than that of base alloy. |
