AMPP CIP LEVEL 1 Test Questions and
Answers - Basic Coating Inspector
Theory
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.
