The deterioration of a metal or alloy that
What is corrosion? results from an electrochemical reaction
with its environment.
Anode
What needs to be present in order for Cathode
corrosion to occur? Metallic Pathway
Electrolyte
The anode is the area of the metal sur-
face that corrodes. The metal oxidizes
What is an anode?
(gains oxygen), causing it to lose mass
and dissolve into the electrolyte.
Oxidation is a chemical reaction that oc-
What is oxidation? curs at the anode where the metal loses
electrons.
The cathode is the area of the metal
What is a cathode?
surface that reduces (loses oxygen).
Reduction is a chemical reaction that oc-
What is reduction? curs at the cathode that involves the met-
al gaining electrons.
The metallic pathway connects the an-
ode to the cathode and allows the pas-
What is the metallic pathway?
sage of electrons generated from the
cathode to the anode.
The electrolyte is the conductive medium
(any solution, like water) in which ions
What is an electrolyte?
are carried from the anode to the cath-
ode.
A barrier coating protects the sub-
strate/metal by providing a chemical and
physical barrier between the metal sur-
What is a barrier coating? face and the environment.
The barrier coating interrupts the elec-
trolyte of the electrochemical cell.

Passivation is when a layer of oxides
What is passivation? form on the surface of a metal that pro-
vides corrosion protection.
To allow the passage of ions from the

anode to the cathode.
A sacrificial coating is a coating that con-
What is a sacrificial coating? tains a metal (usually zinc) that will cor-
rode instead of the metal substrate.
Inhibitive coatings act as aa barricade
to slow down the reaction at the anode,
or cathode, or both. They contain special
What is an inhibitive coating? pigments that react with moisture or oxy-
gen and form a hard, non-reactive sur-
face film that interferes with the corrosion
process.
Pigments
What are the 4 basic components of a Binder/Resins
coating? Solvents
Additives
Pigments are the solid particles that give
specific protective, mechanical, or deco-
rative qualities to the coating.
What is are pigments?
In its unmixed form, pigments are pow-
ders.
Binders/resins are liquids that adhere
What are binders/resins? to the substrate and chemically change
(cure) to form a hard, protective film.
Solvents are the liquid components of
What are solvents? the coating that are responsible for dis-
solving the solid binder/resin.
Additives are special ingredients used
to enhance the performance or certain
What are additives?
properties or characteristics of coatings.
