CORRECT) /ALREADY GRADED A+
What is corrosion? - ANSWER: The deterioration of a metal or alloy that results from
an electrochemical reaction with its environment.
What needs to be present in order for corrosion to occur? - ANSWER: Anode
Cathode
Metallic Pathway
Electrolyte
What is an anode? - ANSWER: The anode is the area of the metal surface that
corrodes. The metal oxidizes (gains oxygen), causing it to lose mass and dissolve into
the electrolyte.
What is oxidation? - ANSWER: Oxidation is a chemical reaction that occurs at the
anode where the metal loses electrons.
What is a cathode? - ANSWER: The cathode is the area of the metal surface that
reduces (loses oxygen).
What is reduction? - ANSWER: Reduction is a chemical reaction that occurs at the
cathode that involves the metal gaining electrons.
What is the metallic pathway? - ANSWER: The metallic pathway connects the anode
to the cathode and allows the passage of electrons generated from the cathode to
the anode.
What is an electrolyte? - ANSWER: The electrolyte is the conductive medium (any
solution, like water) in which ions are carried from the anode to the cathode.
What is a barrier coating? - ANSWER: A barrier coating protects the substrate/metal
by providing a chemical and physical barrier between the metal surface and the
environment.
The barrier coating interrupts the electrolyte of the electrochemical cell.
What is passivation? - ANSWER: Passivation is when a layer of oxides form on the
surface of a metal that provides corrosion protection.
What is the purpose of the electrolyte? - ANSWER: To allow the passage of ions from
the anode to the cathode.
, What is a sacrificial coating? - ANSWER: A sacrificial coating is a coating that contains
a metal (usually zinc) that will corrode instead of the metal substrate.
What is an inhibitive coating? - ANSWER: Inhibitive coatings act as aa barricade to
slow down the reaction at the anode, or cathode, or both. They contain special
pigments that react with moisture or oxygen and form a hard, non-reactive surface
film that interferes with the corrosion process.
What are the 4 basic components of a coating? - ANSWER: Pigments
Binder/Resins
Solvents
Additives
What is are pigments? - ANSWER: Pigments are the solid particles that give specific
protective, mechanical, or decorative qualities to the coating.
In its unmixed form, pigments are powders.
What are binders/resins? - ANSWER: Binders/resins are liquids that adhere to the
substrate and chemically change (cure) to form a hard, protective film.
What are solvents? - ANSWER: Solvents are the liquid components of the coating
that are responsible for dissolving the solid binder/resin.
What are additives? - ANSWER: Additives are special ingredients used to enhance
the performance or certain properties or characteristics of coatings.
They are commonly liquid components that are added in small amounts.
Which 3 materials are commonly used as galvanic anodes for carbon steel? -
ANSWER: Zinc
Magnesium
Aluminum
How does high or low temperature affect the corrosion rate? - ANSWER: High temp =
corrosion rate increases
Low temp = corrosion rate decreases
What is the primary role of a coating inspector? - ANSWER: To ensure compliance
with the contract/project specifications.
Which or the following prevails during conflicting/missing information, specifications
or PDS? - ANSWER: Specifications, unless written and approved permission is given
by the owner or their representative.
