6. Corrosion of Steel and Aluminum in Civil Structures

Try these first

1. 1.

   What is uniform corrosion?

   Hint

   Think about how rust forms on exposed surfaces.

2. 2.

   Name one type of corrosion specific to aluminum.

   Hint

   Think of localized areas of corrosion.

3. 3.

   What type of corrosion occurs evenly over the surface?

   • Uniform Corrosion
   • Pitting Corrosion
   • Galvanic Corrosion

   Hint

   Consider how rust appears on metals.

4. 4.

   True or False: Anodizing can protect aluminum from corrosion.

   • True
   • False

   Hint

   Recall what anodizing does to the oxide layer.

5. 5.

   Design a corrosion prevention strategy for a steel bridge in a coastal environment. Discuss the materials and methods you would use.

   Hint

   Consider environmental factors and start with protection.

6. 6.

   Evaluate the effectiveness of anodizing coatings on aluminum components in marine applications. What factors could affect their performance?

   Hint

   Think about what environmental elements may interact with the coatings.
