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.
, What does a specification document tell the contractor? - ANSWER: What and where
to do, not how to do it.
What is a standard? - ANSWER: Formal document providing guidance for technical
procedures.
What is an Inspection Test Plan (ITP)? - ANSWER: Quality control tool for ensuring
specified requirements are met.
What is surface temperature? - ANSWER: Temperature of the surface being coated.
How does temperature affect solvents? - ANSWER: Affects evaporation time and
curing rates, leading to defects.
What is the minimum and maximum surface temperature for coating? - ANSWER:
Minimum: 40°F (5°C), Maximum: 125°F (40°C).
What should be the substrate temperature for coating application? - ANSWER: At
least 3°C or 5°F above the dew point temperature.
What are the effects of high air temperature? - ANSWER: Shorter pot life, shorter
induction time, and lower viscosity.
What are the effects of high air temperature? - ANSWER: Longer cure time, reduced
re-coat window, potential re-rusting, and wrinkling of the coating.
What are the effects of low air temperature? - ANSWER: Longer pot life, longer
induction time, and higher viscosity.
What are the effects of low air temperature? - ANSWER: Amine blush (bloom) and
adhesion issues.
What is Relative Humidity (RH)? - ANSWER: Amount of water vapor in the air
compared to maximum.
What is Saturation? - ANSWER: When air contains maximum moisture and
condensation forms.
How does high RH affect coating application? - ANSWER: Causes solvent entrapment
and blistering.
What is the recommended RH to prevent moisture on the surface? - ANSWER: Below
85%.
What is the recommended RH to prevent corrosion? - ANSWER: Below 40%.
