Theory Complete Questions and Guide Answers,
100% Verified 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.
