Section 1: Corrosion Fundamentals (Questions 1-30)
1. What is corrosion?
A) A process where metal is protected from environmental damage
B) Deterioration of metal or alloy due to electrochemical reaction
C) A chemical reaction where metal becomes stronger
D) The process of applying protective coatings to metal
Answer: B) Deterioration of metal or alloy due to electrochemical reaction
Explanation: Corrosion is defined as the deterioration of a metal or alloy resulting from an
electrochemical reaction with its environment. This process involves oxidation at the anode
and reduction at the cathode, leading to material loss .
,2. What is the function of an electrolyte in a corrosion cell?
A) Allows flow of electrons between anode and cathode
B) Provides the metallic connection between anode and cathode
C) Allows passage of ions to connect the corrosion cell
D) Prevents the flow of electrical current
Answer: C) Allows passage of ions to connect the corrosion cell
Explanation: The electrolyte is a medium that carries ionic current, allowing ions to pass
between the anode and cathode to complete the corrosion cell .
3. What is the anode in a corrosion cell?
A) The electrode where reduction occurs
B) The electrode where oxidation occurs
C) The electrode that is protected from corrosion
D) The electrode that receives electrons
Answer: B) The electrode where oxidation occurs
Explanation: The anode is the electrode where oxidation occurs, meaning metal atoms lose
electrons and go into solution as ions. This results in the corrosion (deterioration) of the
anodic metal .
4. What is the cathode in a corrosion cell?
A) The electrode where oxidation occurs
B) The electrode where reduction occurs
C) The electrode that corrodes
D) The electrode that gives up electrons
Answer: B) The electrode where reduction occurs
Explanation: The cathode is the electrode where reduction occurs. Reduction is a chemical
, reaction where a substance gains electrons. In a corrosion cell, the cathode is the site
where electrons are consumed .
5. The form of corrosion that has the largest potential for unexpected catastrophic
failure is:
A) Uniform corrosion
B) Pitting corrosion
C) Galvanic corrosion
D) Crevice corrosion
Answer: C) Galvanic corrosion
Explanation: Galvanic corrosion occurs when dissimilar metals are in contact in an
electrolyte, causing the less noble metal to corrode preferentially. This can lead to rapid,
unexpected failure .
6. What is the galvanic series?
A) A listing of metals in order of their melting points
B) A listing of metals in order of reactivity (more or less noble) in seawater
C) A listing of metals in order of their density
D) A listing of metals in order of their hardness
Answer: B) A listing of metals in order of reactivity (more or less noble) in seawater
Explanation: The galvanic series lists metals and alloys in order of their electrochemical
reactivity in seawater, ranking them from more noble (cathodic) to less noble (anodic) .
7. The general rules of galvanic corrosion state that:
A) The more noble metal corrodes when connected to a less noble metal
B) The less noble (or more reactive) metal when connected to a more noble metal will
corrode
