- Chapter 8: Cleaning & Corrosion Control › Inspection
Inspection Inspection for corrosion is a continuing problem and must be handled daily. Overemphasizing a particular corrosion problem when it is discovered and then forgetting about corrosion until the next crisis is an unsafe, costly, and troublesome practice. Most scheduled ... maintenance checklists are complete enough to cover all parts of the aircraft or engine, thus no part of the aircraft goes uninspected. Use these checklists as a general guide when an area is to be inspected for corrosion. Through experience…

Chapter 8: Cleaning & Corrosion Control Corrosion Many aircraft structures are made of metal, and the most insidious form of damage to those structures is corrosion. From the moment the metal is manufactured, it must be protected from the deleterious effects ... environment that surrounds it. This protection can be the introduction of certain elements into the base metal, creating a corrosion-resistant alloy, or the addition of a surface coating of a chemical conversion coating, metal, or paint. While…

Galvanic Corrosion Galvanic corrosion occurs when two dissimilar metals make electrical contact in the presence of an electrolyte. [Figure 8-18] The rate which corrosion occurs depends on the difference in the activities. The greater the difference in activity ... faster corrosion occurs. The rate of galvanic corrosion also depends on the size of the parts in contact. If the surface area of the corroding metal is smaller than the surface area of the less active metal, corrosion is rapid…
