When metallic materials are put into corrosive environments, they tend to have chemical reactions with the air and/or water. The effects of corrosion become evident on the surfaces of these materials. For example, after putting a piece of iron into a corrosive atmosphere for an extended period, it starts rusting due to oxygen interaction with water on the surface of the piece of iron.
Metal equipment lacking any preventive (anti-corrosive) measures, may become rusted both inside and out, depending upon atmospheric conditions and how much of that equipment is exposed to the air. There are a number of methods for preventing corrosion, especially in marine applications. Anti-corrosion measures are of particular importance in environments where high humidity, mist, and salt are factors.
Protection from corrosion
- Anti-corrosion materials
- Stainless steel
- Electrogalvanized cold-rolled steel (SECC), a type of zinc-plated steel, used as a housing to protect electronic components
- Barrier coatings provide a consistent film that forms a chemically resistant barrier and blocks external factors from causing harm. 
- Sacrificial coatings contain certain element (such as aluminum or zinc) which oxidize sacrificially to ensure the protected element remains corrosion free.
- Enclosure design: fully sealed enclosures (at least full IP65) to protect internal electronic components, used in highly salty and damp places
- Painting treatments on the surface: Another way to protect metal housings from corrosion is by using anti-corrosive paint or powder coat on the metallic surface. The function of this coating is to act as a barrier that inhibits contact between chemical compounds or corrosive materials with the metal housing.
