Environments and Their Affects on Corrosion Processes

The environment plays a major role in the selection of materials for corrosion resistance. Environmental factors that may influence corrosion include the environment’s composition, pH level, humidity, wind or water currents, and temperature. These factors exist in the following types of environments, atmospheric, fresh water, saltwater, and soil, which will be discussed in this section. Additional micro-environments, such as specific acid susceptibilities of metals and microorganisms will be covered.
