Abstract
The aluminium alloy AA 6013 is of increasing significance with regard to the aircraft industry. In addition to its mechanical properties, corrosion resistance, especially against local corrosion phenomena (i.e. pitting corrosion and crevice corrosion), is very important in structural applications. In this work, the authors present the use of electrochemical noise analysis (ENA) in combination with a corrosion cell design, which was developed for the investigation of crevice corrosion. It is shown that ENA is a very useful technique for the early detection of crevice corrosion processes in the earliest stages of attack.
