Abstract
Aluminium welded joints are offering greater interest to researchers owing to the replacement of heavy steel structures and reduction in the weight of the components used in the automobile and marine environments. In this study AA6061 and AA8011 have been welded by using the bobbin tool friction stir welding method and by varying the process parameters with the samples being subjected to corrosion environments. The corrosive nature of the welded alloys in the absence and presence of inhibitors (curcumin) has been examined by electrochemical methods and compared with raw samples. The ratio has been observed between 0.075 and 5.42 A cm-2. The results reveal that corrosion control tendency has been improved by the AA6061 and AA8011 aluminium alloy joint in the presence of curcumin extract.
