12.4. Corrosion Resistance Testing

Try these first

1. 1.

   What is the purpose of the salt spray test?

   Hint

   Think about environments where aluminum is used.

2. 2.

   Define pitting corrosion.

   Hint

   It's a type of corrosion you can see.

3. 3.

   What does the salt spray test simulate?

   • Acid rain
   • Marine environments
   • Industrial pollution

   Hint

   Think about where salt spray is commonly found.

4. 4.

   True or False: Anodizing is a process that increases aluminum's corrosion resistance.

   • True
   • False

   Hint

   Consider the protection provided by the natural oxide layer.

5. 5.

   Design a testing regime for a new aluminum alloy meant for coastal applications based on corrosion resistance aspects.

   Hint

   Consider what environments the alloy will be exposed to.

6. 6.

   Evaluate the potential consequences of ignoring pitting corrosion in structural aluminum during design.

   Hint

   Think of what happens when a metal weakens unexpectedly.
