principles of corrosion test with
complete solutions
Corrosion is what type of process of metals returning to their normal state? CORRECT
ANSWERS natural
Corrosion is the electrochecmical *blank* of a metal as a result of its chemical reaction
with the surrounding environment CORRECT ANSWERS deterioration
When two dissimilar metals make electrical contact in the presence of a/an *blank* the
rate at which corrosion occurs depends on the difference in their corrosive tendencies
CORRECT ANSWERS electrolyte
Positively or negatively charged atoms or groups of atoms bound together and are
known as which of the following CORRECT ANSWERS ions
Natural conditions which affect the corrosion process are moisture, temperature, ozone,
sand, dust, solar radiation, insects, birds, microorganisms, and which of the following
CORRECT ANSWERS salt atmosphere
which type of corrosion is most commonly found on aluminum and magnesium alloys
CORRECT ANSWERS pitting
which of the following is an electrolyte CORRECT ANSWERS salt water
which of the following are the four most serious, destructive elements of the desert
climate CORRECT ANSWERS high humidity, high temp, fine dust, ultraviolet radiation
the *blank* of galvanic corrosion also depends on the *blank* of the parts in contact
CORRECT ANSWERS rate, size
which of the following must exist for corrosion to take place CORRECT ANSWERS
metal must be present
When a metal corrodes, the metal atoms lose which of the following and become
positively charged metal ions in the electrolyte CORRECT ANSWERS electrons
Which of the following corrosion types is best represented by the photo (white with
cracks) CORRECT ANSWERS intergranular
Which type of corrosion would you assume has occurred, if the surface grains are lifted
up by the force of expanding corrosion products occurring at the grain boundaries on
aluminum and magnesium parts? CORRECT ANSWERS exfoliation corrosion
