aircraft construction, aircraft are quite susceptible to intergranular corrosion.
Oxidization of this type may not be observable until it is quite severe.
Figure 5 shows exfoliation caused by intergranular corrosion.
Stress corrosion is created by tensile stress in a corrosive environment.
Stress corrosion will cause cracking of metal and is more common in
aluminum, copper, some types of steel, or steel alloys. Be sure to look
closely at bellcranks, landing gear struts, clevis pin joints, and on any part
placed under high stress.
Fretting corrosion occurs between two mating surfaces. The FAA also
refers to this as crevice corrosion and concentration cell corrosion. Although
the surfaces may be designed as stationary, stresses on the aircraft may cause
them to move slightly. As time passes, abrasion will wear through paint or
plating, water will get in, and oxidation will occur. In addition, typically, any
electrolyte within the crevice will have a lower oxygen level and a higher
metal ion level than the area outside of the crevice, which also contributes to
corrosion formation. Figure 6 shows a part with fretting corrosion.
In general, what should avionics technicians do about corrosion? We
can perform preventative maintenance. We should keep the area where we
work clean and wipe down any areas of exposed metal. We should keep
drain holes open. We should ensure the doors are closed during bad weather
and have adequate ventilation during hot days. If the owner is using
