syöpymäkalvon
Syöpymäkalvon, also known as a corrosion film or passive layer, is a protective layer that forms on the surface of a metal when it is exposed to a corrosive environment. This layer is typically very thin and can be composed of metal oxides, hydroxides, or salts. The formation of a syöpymäkalvon is a critical process in preventing further corrosion.
The effectiveness of a syöpymäkalvon depends on its composition, structure, and adherence to the underlying metal.
Different metals form different types of syöpymäkalvon. For example, stainless steels readily form a chromium oxide-based
The formation and stability of syöpymäkalvon can be influenced by various factors including the pH of the
