Questions with correct Answers
Corrosion - Correct Answers -The deterioration of a material, usually a metal, that
results from a reaction with its enviroment
Passivation - Correct Answers -a reduction of the anodic reaction rate of an electrode
involved in corrosion
What are the elements of a corrosion cell? - Correct Answers -Anode, cathode, return
path, electrolyte
Describe what happens at the anode - Correct Answers -Is that part of the metal that
corrodes (dissolves in the electrolyte). It forms positively charged ions that are
conducted to the cathode. Oxidation requires a complementary reaction at the cathode.
What is the function of the electrolyte - Correct Answers -A chemical substance
containing ions that migrate in an electric field
List 3 desirable properties of a coating - Correct Answers -Chemical/water resistance,
adhesion, strength, impact/abrasion resistance
Two broad classifications of a coating are - Correct Answers -Organic (with carbon,
petroleum products) or inorganic (more head resistance
What are 2 primary components of a liquid applied coating - Correct Answers -Pigment
and vehicle (resin and solvent)
Describe the 3 methods by which a coating provides corrosion control - Correct
Answers -Resistance inhibition, oxygen deprivation
what are the three different ways a coating can adhere to the surface - Correct Answers
-Chemical, mechanical, polar
What is the function of the metallic pathway - Correct Answers -(i.e. return path) this
connects the anode and cathode allowing passage of electrons generated at the anode
to the cathode
What is the galvanic series - Correct Answers -A list of metals and alloys arranged
according to their corrosion potentials in a given environment
