What is one of the primary reasons aircraft materials are prone to corrosion?

One of the primary reasons aircraft materials are prone to corrosion is due to environmental factors. Aircraft are often exposed to a variety of elements, including moisture, salt, and pollutants, which can accelerate the corrosion process. For instance, humidity can facilitate the formation of electrochemical cells, where metal surfaces undergo oxidation when in contact with water and oxygen. Additionally, saline environments, such as those found near oceans, greatly increase the risk of corrosion due to the conductive nature of saltwater.

Understanding corrosion in the context of environmental factors highlights the importance of effective materials selection and protective measures in aircraft design and maintenance. By recognizing the various external conditions that contribute to corrosion, professionals in aerospace can implement strategies like proper coatings and regular maintenance routines to mitigate these risks.
