⩥ Cannot always be detected by surface indications. Answer: 253)
Intergranular corrosion in aluminum alloy parts:
⩥ Intergranular Corrosion. Answer: 254) Which of the following may
not be detectable even by careful visual inspection of the surface of
aluminum alloy parts or structures?
⩥ Stiff, non metallic brush. Answer: 255) Corrosion should be removed
from magnesium parts with what?
⩥ The surface of the anodic metal is smaller the the surface area of the
cathodic metal. Answer: 256) Galvanic corrosion is likely to be the most
rapid and severe when:
, ⩥ Contact between two unlike metals.. Answer: 257) Corrosion caused
by galvanic action is the result of what?
⩥ Coating it with linseed oil.. Answer: 258) The interior surface of
sealed structural steel tubing would best be protected against corrosion
by which of the following?
⩥ At the interface of a steel fastener and aluminum alloy inspection plate
in the presence of an electrolyte.. Answer: 259) Galvanic corrosion is
most likely to occur when and/or where?
⩥ Creating comprehensive stresses
(via shot peening) on the metal surface.. Answer: 260) Increased
resistance to stress corrosion cracking can be obtained by:
⩥ Causes rapid and severe corrosion that is very difficult to control..
Answer: 261) Mercury spilled on the aluminum:
⩥ All of the above. Reference 262 in packet.. Answer: 262) Technicians
must be aware of RF radiation hazards associated with transmitting radar
systems. In addition to not transmitting inside of or in close proximity to
