Flash rust

Flash rust is a ubiquitous problem on metallic surfaces, particularly in the aviation sector. This type of corrosion occurs when metallic parts come into contact with moisture and airborne oxygen in combination with iron particles, for example from industrial emissions or brake dust. Special corrosion protection measures are required to minimize the effects of flash rust and ensure long-term corrosion protection.

One effective method of preventing flash rust is the application of anti-corrosion coatings. These coatings form a barrier between the metallic surface and harmful environmental influences. Epoxy resins or polyurethane coatings are often used, which not only form a protective layer, but also have a certain flexibility to withstand the natural expansion and contraction of the material.

Furthermore, corrosion inhibitors are often incorporated into these coatings. These substances react with the metallic surface and form a protective layer that minimizes contact with oxygen and moisture. This slows down or prevents the formation of flash rust. In addition to coatings, special anti-corrosion agents in the form of oils or waxes are also used to protect metallic surfaces from harmful influences. These agents penetrate the microstructures of the metal and provide additional protection against corrosion.

Overall, effective flash rust corrosion protection is vital to ensure the durability and integrity of metallic components. The application of suitable coatings and protective agents plays a central role in effectively counteracting the negative effects of flash rust.
