Examining Corrosion Processes of Low-Alloy Steel

The M4 TORNADO allows to analyze the elemental distribution of coated sample areas. If coatings are very thin it is possible to enlarge these areas of different coatings by polishing at a small angle. This preparation technique was used to analyze the corrosion processes of differently treated samples of low-alloy steel. The distribution of all elements – base material (steel), coating material (Zn and ZnAl alloy) and the elements used for treatment – could be distinguished. The information on their distribution helps to get a better understanding of the corrosion process. It shows that the susceptibility to corrosion is reduced by adding Al in a coating.
