WebApr 5, 2016 · In the passivating process, the amount of dissolved metal ions (for example zinc and iron) in the passivation solution increases the longer the solution is used. This results in a reduced corrosion resistance at elevated temperatures. Adding a top coat after this process improves the corrosion resistance but has an increased cost. WebFeb 18, 2024 · So the passivation process does two things: first, it removes all the steel particles left behind by the machine/tooling process. Now, it won’t remove everything, so it’s very important before we go into the passivation process, that our product is clean.
