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