AMPP CIP LEVEL 1 - Basic Coating Inspector Theory –questions with answers
What are Volatile Organic Compounds (VOCs)? - ** VERIFIED ANSWERS **✔✔Chemicals that
easily evaporate at room temperature.
What are solvents? - ** VERIFIED ANSWERS **✔✔Substances that dissolve other substances to
form a solution.
Why can solvents in coatings be harmful? - ** VERIFIED ANSWERS **✔✔Because they can release
VOCs into the air.
What are some examples of solvents used in coatings? - ** VERIFIED ANSWERS **✔✔Acetone,
toluene, xylene, and ethyl acetate.
What are three commonly used galvanic anodes for carbon steel? - ** VERIFIED ANSWERS
**✔✔Zinc, Aluminum, and Magnesium
What is the effect of temperature on corrosion rate? - ** VERIFIED ANSWERS **✔✔Decrease in
temperature decreases corrosion rate.
What is an electrolyte? - ** VERIFIED ANSWERS **✔✔A medium that carries ionic current.
What is sacrificial coating? - ** VERIFIED ANSWERS **✔✔A type of coating that becomes the
anode of an electrochemical cell.
What is the role of binders in coating? - ** VERIFIED ANSWERS **✔✔Binders form a stable film
that retains its properties.
,What is a barrier coating? - ** VERIFIED ANSWERS **✔✔A coating that interrupts the electrolyte
of an electrochemical cell.
What are two environments most susceptible to corrosion? - ** VERIFIED ANSWERS **✔✔Marine
Environment, Chemical with High Humidity Environment
What is the direction of electron flow in an oxidation reaction? - ** VERIFIED ANSWERS
**✔✔From the anode to the cathode through the metallic path.
What is the role of binders? - ** VERIFIED ANSWERS **✔✔Binders bonds pigments together and
adhere to surface.
What are solvents? - ** VERIFIED ANSWERS **✔✔Solvents are liquids that dissolve the solid
resins.
What is the purpose of pigments? - ** VERIFIED ANSWERS **✔✔Pigments hide the substrates,
provide decorative color, and enhance desired properties.
What are additives? - ** VERIFIED ANSWERS **✔✔Additives are special purpose ingredients used
to enhance the performance.
What are vehicles? - ** VERIFIED ANSWERS **✔✔Vehicles are the liquid portions of the coating.
What is corrosion? - ** VERIFIED ANSWERS **✔✔Deterioration of metal or alloy due to
electrochemical reaction.
What is passivation? - ** VERIFIED ANSWERS **✔✔Layer of oxides on metal surface for corrosion
protection.
Give an example of a metal that undergoes passivation. - ** VERIFIED ANSWERS **✔✔Stainless
steel
,What is an anode? - ** VERIFIED ANSWERS **✔✔The electrode where oxidation occurs.
What is a cathode? - ** VERIFIED ANSWERS **✔✔The electrode where reduction occurs.
What is a metallic pathway? - ** VERIFIED ANSWERS **✔✔The conductive path for electrons to
flow.
What are electrolytes? - ** VERIFIED ANSWERS **✔✔Substances that conduct electricity when
dissolved in water.
What is the function of an electrolyte in corrosion? - ** VERIFIED ANSWERS **✔✔Allows passage
of ions in corrosion cell.
What is the function of a metallic pathway in corrosion? - ** VERIFIED ANSWERS **✔✔Allows
flow of electrons in corrosion cell.
What is the galvanic series? - ** VERIFIED ANSWERS **✔✔Listing of metals in order of reactivity.
What is the general rule of the galvanic series? - ** VERIFIED ANSWERS **✔✔Less noble metal
connected to a more noble metal will corrode preferentially.
What is localized corrosion? - ** VERIFIED ANSWERS **✔✔Corrosion that occurs in specific areas.
What are the types of localized corrosion? - ** VERIFIED ANSWERS **✔✔Pitting and crevice
corrosion.
Why is localized corrosion concerning? - ** VERIFIED ANSWERS **✔✔Damage is concentrated
and can lead to structural failure.
What is general corrosion? - ** VERIFIED ANSWERS **✔✔Uniform loss of material over entire
surface.
, How does general corrosion affect the surface? - ** VERIFIED ANSWERS **✔✔Results in general
thinning of affected surface.
Is general corrosion easy to inspect? - ** VERIFIED ANSWERS **✔✔Yes, it is relatively easy to
inspect.
Does general corrosion cause catastrophic failure? - ** VERIFIED ANSWERS **✔✔No, it does not
cause catastrophic failure.
What is inorganic convertible thermosetting? - ** VERIFIED ANSWERS **✔✔Coating that
undergoes irreversible chemical changes upon curing.
What is inorganic non-convertible thermoplastic? - ** VERIFIED ANSWERS **✔✔Coating that
softens upon heating and hardens upon cooling.
What are the primary components of a liquid applied coating? - ** VERIFIED ANSWERS
**✔✔Pigments and Vehicle (Resin or Binder and Solvent)
What is a sacrificial coating system? - ** VERIFIED ANSWERS **✔✔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? - ** VERIFIED
ANSWERS **✔✔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? - ** VERIFIED ANSWERS **✔✔To create a physical
barrier between the metal surface and the corrosive environment, preventing direct contact and
corrosion.
What is an inhibitive coating? - ** VERIFIED ANSWERS **✔✔A coating that releases corrosion
inhibitors to slow down or prevent corrosion on the metal surface.
