What is the purpose of corrosion identification?

• To effectively and efficiently perform aircraft maintenance

• To detect and prevent corrosion from damaging equipment and aircraft

• To prevent exfoliation

• To reverse damage caused by corrosion

This type of corrosion is built up between the contacting points of dissimilar metals.

• Pitting

• Galvanic

• Stress

• Exfoliation

This type of corrosion is identified by a lifting or swelling of a metal surface.

• Pitting

• Galvanic

• Exfoliation

• Stress

This is a form of galvanic corrosion and occurs as metal fatigue below its rated strength due to excessive loads and corrosion.

• Exfoliation

• Stress

• Galvanic

• Pitting

This type of corrosion is initiated by the oxidation process.

• Exfoliation

• Stress

• Galvanic

• Pitting

This type of corrosion occurs on polished surfaces and is caused by a direct chemical attack on uprotected surfaces.

• Pitting

• Galling

• Uniform Etch

• Galvanic

This type of corrosion attacks metal grain boundaries.

• Galvanic

• Intergranular

• Pitting

• Exfoliation
