AND CORRECT ANSWERS EXAMPREP
STUDY SHEET
●● Electrolyte
Answer: Any solution capable of conducting electricity
●● Metallic Pathway
Answer: Allows the passage of electrons between the anode and cathode
●● Cathode
Answer: The area of the metal that corrodes
●● Galvanic Series
Answer: List of metals and alloys arranged according to their reactivity
●● Which 3 factors affect the rate of corrosion?
Answer: Concentration of oxygen, concentration of water, natural salts
manufactured salts, temperature, earth metals, atmospheric moisture.
●● Barrier Coatings
,Answer: Protect the substrate by providing a chemical and physical
barrier between the metal and the environment.
●● Sacrificial Coatings
Answer: Coatings that uses a metal that is anodic to steel and corrodes
instead of the metal substrate.
●● Inhibitive Coatings
Answer: Actively slow down the reaction occurring at the anode,
cathode, or both (in addition to being a barrier); must be a primer, must
be in contact with the substrate
●● What 4 components make up a coating?
Answer: Pigments, binders, solvents, additives.
●● Pigments
Answer: Solid particles used to give a specific protective, mechanical, or
decorative qualities to a coating.
●● Binders
Answer: Liquids that adhere to the substrate and chemically change to
form a hard protective film.
●● Solvents
, Answer: Liquid component of the coating that is responsible for
dissolving the solid binder.
●● Additives
Answer: Special purpose ingredients used to enhance the performance,
or more specifically, certain properties or characteristics of the coating.
●● Which component of a coating can contain harmful volatile organic
compounds?
Answer: Solvents
●● Base on the galvanic series, which 3 materials are commonly used as
galvanic anodes for carbon steel?
Answer: Zinc, aluminum, magnesium
●● A decrease in temperature will generally cause the corrosion rate to?
Answer: decrease
●● The electrolyte is a medium that carries the following type of
current?
Answer: Ionic
●● Which type of coating is manufactured with specific components that
become the anode of the electrochemical cell?
