| Many alloys used in aircraft construction are sensitive to a form of corrosion known as __. | Stress Corrosion Cracking |
| __ occurs when different metals are in contact with each other and an electrolyte. | Galvanic Corrosion |
| Which corrosion is recognized by the presence of a buildup of corrosion deposits at the joint between the metals. | Galvanic Corrosion |
| __ is a form of extremely localized attack that results in holes in the metal. | Pitting Corrosion |
