Anti-corrosion properties

Definition

Anti-corrosion properties refer to the characteristics and capabilities of materials or coatings that prevent or slow down the deterioration caused by corrosion, which is a chemical reaction between materials, typically metals, and their environment. These properties are especially crucial in aerospace applications where components face harsh conditions, as they help maintain structural integrity and extend the lifespan of aircraft parts.
