Often due to a lack of structural protection (paint chips), corrosion can weaken the entire aircraft.

A humid and saline environment can also accelerate the oxidation of metal alloys used in aeronautical materials.

The process is a chemical treatment, consisting of depositing a thin coating on the surface of a material, giving it specific chemical functionalities.

After removing all traces of corrosion, applied by spraying, chromating gives aluminum exceptional resistance to corrosion, even without the application of another coating.

These treatments ensure good adhesion of paints and adhesives.
