Salt spray test

Sample 1

was cleaned with Greinox 1000

Sample 3

was cleaned with Greinox 2000


After 180 hours in the salt spray chamber there is no corrosion on the welding seams.
This shows that passivation has occured. The welding seam in sample 3 shows obvious signs of crevice corrosion. This means that oxides cannot be completely removed from crevices through a surface treatment. Here, the use of protective gases or backwelding is needed.
