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 Anode Cathode Metallic Pathway
order for corrosion to occur? 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 To allow the passage of ions from
electrolyte? 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
