QUESTION 1
What is corrosion?
A. The formation of a protective oxide layer on metal
B. The deterioration of a metal or alloy due to electrochemical reaction
C. The process of applying a protective coating to metal
D. The mechanical wear of metal surfaces
Correct Answer: B. The deterioration of a metal or alloy due to electrochemical
reaction
Rationale: Corrosion is defined as the deterioration of a metal or alloy due to
electrochemical reaction with its environment. This is a fundamental concept in coatings
inspection, as the primary purpose of protective coatings is to prevent corrosion.
QUESTION 2
Which of the following is NOT a factor that affects the rate of corrosion?
A. Humidity
B. Temperature
C. Oxygen
D. Coating color
Correct Answer: D. Coating color
Rationale: The five factors that affect the rate of corrosion are: humidity, oxygen, chemical
salts, pollutants, and temperature. Coating color does not affect the corrosion rate.

QUESTION 3
What is the direction of electron flow in an oxidation reaction?
A. From the cathode to the anode through the metallic path
B. From the anode to the cathode through the metallic path
C. Through the electrolyte only
D. Random in all directions
Correct Answer: B. From the anode to the cathode through the metallic path
Rationale: In an electrochemical corrosion cell, electrons flow from the anode (where
oxidation occurs) to the cathode through the metallic path. The electrolyte carries ionic
current between the anode and cathode.
QUESTION 4
What is an electrolyte?
A. A metal that resists corrosion
B. A medium that carries ionic current
C. A protective coating layer
D. A type of paint additive
Correct Answer: B. A medium that carries ionic current
Rationale: An electrolyte is a medium that carries ionic current between the anode and
cathode in an electrochemical corrosion cell. This is essential for the corrosion process to
occur.
QUESTION 5
Three commonly used galvanic anodes for carbon steel are:
A. Copper, silver, and gold
B. Zinc, aluminum, and magnesium
Sure pass
,3
C. Lead, tin, and nickel
D. Chromium, titanium, and platinum
Correct Answer: B. Zinc, aluminum, and magnesium
Rationale: Zinc, aluminum, and magnesium are the three commonly used galvanic anodes
for cathodic protection of carbon steel. These metals are more electrochemically active
than steel and sacrificially corrode to protect the steel structure.
QUESTION 6
What is a sacrificial coating?
A. A coating that is easily removed
B. A type of coating that becomes the anode of an electrochemical cell
C. A coating that is applied sacrificially for decorative purposes
D. A coating that is applied to the cathode
Correct Answer: B. A type of coating that becomes the anode of an electrochemical
cell
Rationale: A sacrificial coating becomes the anode of an electrochemical cell, corroding
preferentially to protect the underlying metal substrate. This provides cathodic protection
to the structure.
QUESTION 7
What is the effect of temperature on corrosion rate?
A. Increase in temperature increases corrosion rate
B. Increase in temperature decreases corrosion rate
C. Temperature has no effect on corrosion rate
D. Only extreme temperatures affect corrosion rate
Correct Answer: A. Increase in temperature increases corrosion rate
Sure pass
, 4
Rationale: An increase in temperature generally increases the corrosion rate because
chemical reactions (including electrochemical reactions) proceed faster at higher
temperatures.
QUESTION 8
What is general corrosion?
A. Corrosion that occurs only at specific points
B. Uniform loss of material over the entire surface
C. Corrosion that is caused by mechanical stress
D. Corrosion that occurs only in marine environments
Correct Answer: B. Uniform loss of material over the entire surface
Rationale: General corrosion results in relatively uniform loss of material over the entire
exposed surface. It is relatively easy to inspect and does not typically cause catastrophic
failure, unlike localized forms of corrosion.
QUESTION 9
Why is localized corrosion concerning?
A. It is difficult to see
B. Damage is concentrated and can lead to structural failure
C. It only occurs in specific environments
D. It is always caused by coatings
Correct Answer: B. Damage is concentrated and can lead to structural failure
Rationale: Localized corrosion is concerning because the damage is concentrated in a
small area, which can lead to rapid perforation and structural failure. Forms of localized
corrosion include pitting, crevice corrosion, and stress corrosion cracking.
