Is chromate treatment necessary after zinc plating of Silvec?
Q: Is chromate treatment necessary for zinc-coated surfaces? A: In the case of electro-galvanized coatings, chromate treatment is applied to most products after zinc plating. Zinc coatings are very prone to rust. For zinc plating on iron materials, the zinc coating helps to delay the onset of red rust by corroding (forming white rust), which prevents the occurrence of red rust. Chromate treatment is performed to prevent the formation of white rust (for rust prevention purposes). The corrosion resistance against the formation of white rust depends on the performance of the chromate coating.
