Question 11

Question
Anytime you see magnesium, it will always be
Answer
  • Primed and top coated due to its low resistance to corrosion
  • Heavily lubricated due primarily to its low resistance to corrosion
  • Free from lubricants due to its high resistance to corrosion
  • Bare due to primarily due to its high resistance to corrosion

Question 12

Question
Aluminum's formation of a tightly adhering oxide film
Answer
  • Prevents it from being primed and top coated
  • Offers reduced resistance under all corrosive conditions
  • Provides increased resistance under mild corrosive conditions
  • Requires heavy lubrication to prevent further degradation of structural integrity

Question 13

Question
In unprotected, ferrous metal surfaces are
Answer
  • Highly resistant to corrosion
  • Easily corroded if moisture is absent
  • Easily corroded if moisture is present
  • Easily corroded in the presence of high-temperature exhaust

Question 14

Question 15

Question
The main cause of the corrosion of spot welded metals is the
Answer
  • Excessive use of lubricant attacking the structure
  • Dissimilar metal contact from the binding agents used
  • Entrance and entrapment of corrosive agents between the layers of metals
  • heat damage to the anti-corrosion coating caused by the welding process

Question 16

Question
Piano hinges are prime spots for corrosion because they are natural traps for dirt, salt, and moisture, and
Answer
  • Dissimilar metal contact between the steel pin and the aluminum hinge tangs
  • Residual oil quite often masks small quantities of water that set up hidden corrosion cells
  • Their constant actuation by maintenance personnel results in excessive wear of their finishes
  • Their protective finish is very often blistered by heat, blasted away by the high-velocity gases, and abraded by spent shell casings and solid particles from gun and rocket exhausts
