WebJul 13, 2024 · A conversion coating that tends to give off a greenish colour doesn't have the silver particles spaced uniformly. The study doesn't exactly say what causes this, yet states that certain impurities that remain on the surface may cause corrosion or disruption of the silver particle spacing thus giving off a greenish look. WebPassivation is a post-fabrication process that is performed after welding, grinding, cutting and other machining operations that manipulate stainless steel. Under ideal …
