What is corrosion? 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 Anode
occur? Cathode
Metallic Pathway
Electrolyte
What is an anode? 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? Oxidation is a chemical reaction that occurs at the anode where the metal loses
electrons.
What is a cathode? The cathode is the area of the metal surface that reduces (loses oxygen).
What is reduction? Reduction is a chemical reaction that occurs at the cathode that involves the
metal gaining electrons.
What is the metallic pathway? 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? 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? 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? 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? To allow the passage of ions from the anode to the cathode.
What is a sacrificial coating? 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? 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? Pigments
Binder/Resins
Solvents
Additives
What is are pigments? 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? Binders/resins are liquids that adhere to the substrate and chemically change
(cure) to form a hard, protective film.
What are solvents? Solvents are the liquid components of the coating that are responsible for
dissolving the solid binder/resin.
What are additives? 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 Zinc
anodes for carbon steel? Magnesium
Aluminum
How does high or low temperature affect the corrosion High temp = corrosion rate increases
rate?
Low temp = corrosion rate decreases
What is the primary role of a coating inspector? To ensure compliance with the contract/project specifications.
Which or the following prevails during Specifications, unless written and approved permission is given by the owner
conflicting/missing information, specifications or PDS? or their representative.
What is recoat time? How long you have to wait before you can apply another coat.
What is induction time? How long you have to wait after mixing until the product can be applied.
