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