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.
由于在汽车和海洋环境中使用的重型钢结构的替代和部件重量的减轻，铝焊接接头引起了研究人员的更大兴趣。在本研究中，AA6061和AA8011采用筒管工具搅拌摩擦焊法焊接，并根据试样所处的腐蚀环境改变工艺参数。用电化学方法研究了在没有和存在抑制剂(姜黄素)的情况下焊接合金的腐蚀性质，并与原始样品进行了比较。比值在0.075 ~ 5.42 A cm-2之间。结果表明，姜黄素提取物对AA6061和AA8011铝合金接头的腐蚀控制倾向有所改善。
