SECTION 1: CORROSION FUNDAMENTALS (Questions 1-15)
QUESTION 1
What is the definition of corrosion according to AMPP?
A) The chemical breakdown of organic materials
B) The deterioration of a metal or alloy that results from an electrochemical
reaction with its environment
C) The physical wear of a surface due to friction
D) The oxidation of non-metallic materials
Rationale: Corrosion is defined as the deterioration of a metal or alloy that results from
an electrochemical reaction with its environment. This process involves the transfer of
electrons between the metal and its surroundings, leading to the breakdown of the metal's
structure. AMPP (Association for Materials Protection and Performance) uses this definition
as the standard .

QUESTION 2
What four elements must be present for corrosion to occur?
A) Anode, Cathode, Metallic Pathway, Electrolyte
B) Oxygen, Water, Metal, Heat
C) Salt, Moisture, Air, Metal
D) Anode, Cathode, Salt, Water
Rationale: For corrosion to occur, four elements must be present: an anode (where
oxidation occurs), a cathode (where reduction occurs), a metallic pathway (connects anode
to cathode allowing electron flow), and an electrolyte (conductive medium carrying ions).
If any one element is missing, corrosion will not occur .
QUESTION 3
What is the anode in an electrochemical corrosion cell?
A) The area of the metal surface that reduces and gains electrons
B) The area of the metal surface that corrodes and oxidizes
C) The conductive medium that carries ions
D) The pathway that connects the anode and cathode
Rationale: In an electrochemical corrosion cell, the anode is the area of the metal surface
that corrodes. At the anode, the metal undergoes oxidation, losing electrons and dissolving
into the electrolyte. This is where the actual metal loss occurs .

What is the cathode in an electrochemical corrosion cell?
A) The area of the metal surface that corrodes and oxidizes
B) The area of the metal surface that reduces and gains electrons
C) The conductive medium that carries ions
D) The pathway that connects the anode and cathode
Rationale: The cathode is the area of the metal surface that reduces and gains electrons.
At the cathode, reduction reactions occur, such as the reduction of oxygen or hydrogen
ions. The cathode does not corrode; it is protected by the electrons received from the
anode .
QUESTION 5
What is an electrolyte in the context of corrosion?
A) The area where oxidation occurs
B) The area where reduction occurs
C) The metallic connection between anode and cathode
D) A medium that carries ionic current
Rationale: The electrolyte is the conductive medium (such as water or any aqueous
solution) in which ions are carried from the anode to the cathode. The electrolyte
completes the electrical circuit in the corrosion cell by allowing the movement of ions .
QUESTION 6
What is the metallic pathway in an electrochemical corrosion cell?
Sure pass
, 4
A) The conductive medium that carries ions
B) The area where oxidation occurs
C) The area where reduction occurs
D) The connection between the anode and cathode that allows the passage of
electrons
Rationale: The metallic pathway connects the anode to the cathode and allows the
passage of electrons generated from the anode to the cathode. This is typically the metal
substrate itself .
QUESTION 7
What is passivation?
A) The process of applying a protective coating
B) The formation of a layer of oxides on the surface of a metal that provides
corrosion protection
C) The removal of oxide layers from metal surfaces
D) The electrochemical reaction that causes metal loss
Rationale: Passivation is when a layer of oxides forms on the surface of a metal that
provides corrosion protection. This oxide layer acts as a barrier, slowing down further
corrosion. Stainless steel, for example, is protected by a passive chromium oxide film .
QUESTION 8
How does temperature affect the rate of corrosion?
Sure pass
