6.2.1. Common Aluminum Corrosion Forms

Try these first

1. 1.

   What is pitting corrosion?

   Hint

   Think about environments that could lead to isolated areas of corrosion.

2. 2.

   Name one preventive measure against galvanic corrosion.

   Hint

   Consider how two different metals can interact.

3. 3.

   What form of corrosion is characterized by localized pits on the aluminum surface?

   • Galvanic Corrosion
   • Pitting Corrosion
   • Filiform Corrosion

   Hint

   Think about how certain conditions might lead to localized damage.

4. 4.

   True or False: Galvanic corrosion occurs when aluminum is in contact with another aluminum piece.

   • True
   • False

   Hint

   Consider what types of metals can be involved in galvanic reactions.

5. 5.

   Design a maintenance plan for aluminum structures situated near a coastal environment. Include inspection frequency and preventive measures.

   Hint

   Consider environmental impact and maintenance best practices.

6. 6.

   Evaluate a case study where an aluminum structure suffered from filiform corrosion. Identify flaws in the initial design and propose a revised approach.

   Hint

   Evaluate initial design assumptions versus real-world exposures.
