When dissimilar metals are in contact with one another in the presence of an electrolyte, galvanic action occurs, resulting in the deterioration of the metal with the lower galvanic number. The electrolyte may be rain water running from one surface to another, or moisture from the air containing enough acid to cause it to act as an electrolyte.

Passivation of Stainless Steel - electrohio

We take care in passivating austenitic or low chromium grades of stainless steel. Request a passivation quote. We do not recommend passivating stainless steel that has a carbonized/nitrided surface, because nitric acid will dissolve the surface and reduce the size of the component. It is important that you identify the type of stainless steel ...

If rust is found on metal, does acid ... - UCSB Science Line

Rust is what happens when you oxidize a metal. For example, you form Fe 2 O 3 on Fe (when talking about iron or steel). Acid can dissolve the rust (Fe 2 O 3). However, the acid will also oxidize the metal further, forming more rust, and dissolving that rust. In the simplest case, lets imagine hydrochloric acid and iron (HCl and Fe).
