What are Volatile Organic Compounds (VOCs)? - CORRECT ANSWER -
Chemicals that easily evaporate at room temperature.
What are solvents? - CORRECT ANSWER -
Substances that dissolve other substances to form a solution.
Why can solvents in coatings be harmful? - CORRECT ANSWER -
Because they can release VOCs into the air.
What are some examples of solvents used in coatings? - CORRECT ANSWER -
Acetone, toluene, xylene, and ethyl acetate.
What are three commonly used galvanic anodes for carbon steel? - CORRECT ANSWER -
Zinc, Aluminum, and Magnesium
What is the effect of temperature on corrosion rate? - CORRECT ANSWER -
Decrease in temperature decreases corrosion rate.
What is an electrolyte? - CORRECT ANSWER -A medium that carries ionic current.
What is sacrificial coating? - CORRECT ANSWER -
A type of coating that becomes the anode of an electrochemical cell.
What is the role of binders in coating? - CORRECT ANSWER -
Binders form a stable film that retains its properties.
,What is a barrier coating? - CORRECT ANSWER -
A coating that interrupts the electrolyte of an electrochemical cell.
What are two environments most susceptible to corrosion? - CORRECT ANSWER -
Marine Environment, Chemical with High Humidity Environment
What is the direction of electron flow in an oxidation reaction? - CORRECT ANSWER -
From the anode to the cathode through the metallic path.
What is the role of binders? - CORRECT ANSWER -
Binders bonds pigments together and adhere to surface.
What are solvents? - CORRECT ANSWER -Solvents are liquids that dissolve the solid resins.
What is the purpose of pigments? - CORRECT ANSWER -
Pigments hide the substrates, provide decorative color, and enhance desired properties.
What are additives? - CORRECT ANSWER -
Additives are special purpose ingredients used to enhance the performance.
What are vehicles? - CORRECT ANSWER -Vehicles are the liquid portions of the coating.
What is corrosion? - CORRECT ANSWER -
Deterioration of metal or alloy due to electrochemical reaction.
What is passivation? - CORRECT ANSWER -
Layer of oxides on metal surface for corrosion protection.
,Give an example of a metal that undergoes passivation. - CORRECT ANSWER -Stainless steel
What is an anode? - CORRECT ANSWER -The electrode where oxidation occurs.
What is a cathode? - CORRECT ANSWER -The electrode where reduction occurs.
What is a metallic pathway? - CORRECT ANSWER -The conductive path for electrons to flow.
What are electrolytes? - CORRECT ANSWER -
Substances that conduct electricity when dissolved in water.
What is the function of an electrolyte in corrosion? - CORRECT ANSWER -
Allows passage of ions in corrosion cell.
What is the function of a metallic pathway in corrosion? - CORRECT ANSWER -
Allows flow of electrons in corrosion cell.
What is the galvanic series? - CORRECT ANSWER -Listing of metals in order of reactivity.
What is the general rule of the galvanic series? - CORRECT ANSWER -
Less noble metal connected to a more noble metal will corrode preferentially.
What is localized corrosion? - CORRECT ANSWER -Corrosion that occurs in specific areas.
What are the types of localized corrosion? - CORRECT ANSWER -
Pitting and crevice corrosion.
, Why is localized corrosion concerning? - CORRECT ANSWER -
Damage is concentrated and can lead to structural failure.
What is general corrosion? - CORRECT ANSWER -
Uniform loss of material over entire surface.
How does general corrosion affect the surface? - CORRECT ANSWER -
Results in general thinning of affected surface.
Is general corrosion easy to inspect? - CORRECT ANSWER -
Yes, it is relatively easy to inspect.
Does general corrosion cause catastrophic failure? - CORRECT ANSWER -
No, it does not cause catastrophic failure.
What is inorganic convertible thermosetting? - CORRECT ANSWER -
Coating that undergoes irreversible chemical changes upon curing.
What is inorganic non-convertible thermoplastic? - CORRECT ANSWER -
Coating that softens upon heating and hardens upon cooling.
What are the primary components of a liquid applied coating? - CORRECT ANSWER -
Pigments and Vehicle (Resin or Binder and Solvent)
What is a sacrificial coating system? - CORRECT ANSWER -
A coating system where a more active metal is applied over a less active metal to act as an
anode and protect the underlying metal.
