1. How is the process of steel corrosion ALWAYS described?
A. Chemical
B. Electrochemical
C. Physical
D. Mechanical
Correct Answer: B. Electrochemical
Rationale: The process of steel corrosion is always described as an
electrochemical process, involving the transfer of electrons between
an anode and a cathode through a metallic pathway and an
electrolyte.
2. What are the four essential elements of a corrosion cell?
,A. Anode, Cathode, Resistance, Voltage
B. Anode, Cathode, Electrolyte, Metallic Pathway
C. Anode, Cathode, Salt, Water
D. Anode, Cathode, Oxygen, Hydrogen
Correct Answer: B. Anode, Cathode, Electrolyte, Metallic Pathway
Rationale: The four essential components of a corrosion cell are the
anode (where metal dissolves), the cathode (where reduction occurs),
the electrolyte (which allows ion passage), and the metallic pathway
(which allows electron flow).
3. What is the function of the electrolyte in a corrosion cell?
A. Allows the flow of electrons
B. Allows the passage of ions to connect the corrosion cell
C. Prevents corrosion
D. Accelerates the corrosion process
Correct Answer: B. Allows the passage of ions to connect the
corrosion cell
Rationale: The electrolyte is the medium that allows the passage of
ions, completing the electrical circuit in the corrosion cell.
,4. What is the function of the metallic pathway in a corrosion cell?
A. Allows the passage of ions
B. Allows the flow of electrons to connect the corrosion cell
C. Prevents corrosion
D. Dissolves the metal
Correct Answer: B. Allows the flow of electrons to connect the
corrosion cell
Rationale: The metallic pathway provides a connection between the
anode and cathode, allowing the flow of electrons to complete the
corrosion circuit.
5. Corrosion occurring uniformly across a surface is called _____.
A. General corrosion
B. Local corrosion
C. Pitting
D. Crevice corrosion
Correct Answer: A. General corrosion
, Rationale: General corrosion results in a relatively uniform loss of
material over the entire surface, causing general thinning. It is
relatively easy to inspect and does not typically cause catastrophic
failures.
6. Which type of corrosion is typically of the MOST concern as
damage is concentrated and loss of integrity or structural failure can
result?
A. General corrosion
B. Localized corrosion
C. Uniform corrosion
D. Atmospheric corrosion
Correct Answer: B. Localized corrosion
Rationale: Localized corrosion, including pitting and crevice
corrosion, is typically of the most concern because damage is
concentrated and loss of integrity or structural failure can result.
7. What is the galvanic series?
A. A listing of metals by weight
B. A listing of metals in order of reactivity (more or less noble) in
seawater at 25°C
