Fuel sometimes contain sulphates which melt at very low temperature during combustion. Crevice Corrosion Crevice corrosion occurs in confined spaces where a gap is large enough to allow the ingress of corrodent however are small to allow it to stay stagnant. The company has successful projects not only in Russia, but also abroad, and is ready for new challenges. These small surface openings may penetrate deeply into structural members and cause damage completely out of proportion to its surface appearance. If the zinc coating is scratched, the zinc will act as an anode and will still corrode before the steel or iron. #corrosionprotection. Corrosion is the rusting of iron pH indicator should be used to test for rusting Rusting takes place in the presence of oxygen only Rusting will not take place if water is not present Salt is required for rusting to take place Rusting will occur faster in sea water than tap water Problem Rusting occurs faster in salt solution than in pure water.
