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