- Chapter 8: Cleaning & Corrosion Control › Corrosion of Ferrous Metals › Removal of Corrosion from Highly Stressed Steel Parts
Removal of Corrosion from Highly Stressed Steel Parts Any corrosion on the surface of a highly-stressed steel part is potentially dangerous, and the careful removal of corrosion products is required. Surface scratches or change in surface structure from overheating ... also cause sudden failure of these parts. Corrosion products must be removed by careful processing, using mild abrasive papers, such as rouge or fine grit aluminum oxide or fine buffing compounds on cloth buffing wheels. Nonwoven abrasive pads can also…
- Chapter 8: Cleaning & Corrosion Control › Corrosion Removal
Corrosion Removal In general, any complete corrosion treatment involves cleaning and stripping of the corroded area, removing as much of the corrosion products as practicable, neutralizing any residual materials remaining in pits and crevices, restoring protective surface films, and applying ... temporary or permanent coatings or paint finishes. Repair of corrosion damage includes removal of all corrosion and corrosion products. When the corrosion damage is severe and exceeds the damage limits set by the aircraft or parts manufacturer, the part must…
- Chapter 8: Cleaning & Corrosion Control › Galvanic Corrosion › Common Corrosive Agents
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…
