Acetone, toluene, xylene, and ethyl acetate.



What are three commonly used galvanic anodes for carbon steel? - CORRECT ANSWER -
Zinc, Aluminum, and Magnesium



What is the effect of temperature on corrosion rate? - CORRECT ANSWER -
Decrease in temperature decreases corrosion rate.



What is an electrolyte? - CORRECT ANSWER -A medium that carries ionic current.



What is sacrificial coating? - CORRECT ANSWER -
A type of coating that becomes the anode of an electrochemical cell.



What is the role of binders in coating? - CORRECT ANSWER -
Binders form a stable film that retains its properties.

,What is a barrier coating? - CORRECT ANSWER -
A coating that interrupts the electrolyte of an electrochemical cell.



What are two environments most susceptible to corrosion? - CORRECT ANSWER -
Marine Environment, Chemical with High Humidity Environment



What is the direction of electron flow in an oxidation reaction? - CORRECT ANSWER -
From the anode to the cathode through the metallic path.



What is the role of binders? - CORRECT ANSWER -
Binders bonds pigments together and adhere to surface.



What are solvents? - CORRECT ANSWER -Solvents are liquids that dissolve the solid resins.



What is the purpose of pigments? - CORRECT ANSWER -
Pigments hide the substrates, provide decorative color, and enhance desired properties.



What are additives? - CORRECT ANSWER -
Additives are special purpose ingredients used to enhance the performance.



What are vehicles? - CORRECT ANSWER -Vehicles are the liquid portions of the coating.



What is corrosion? - CORRECT ANSWER -
Deterioration of metal or alloy due to electrochemical reaction.



What is passivation? - CORRECT ANSWER -
Layer of oxides on metal surface for corrosion protection.

,Give an example of a metal that undergoes passivation. - CORRECT ANSWER -Stainless steel



What is an anode? - CORRECT ANSWER -The electrode where oxidation occurs.



What is a cathode? - CORRECT ANSWER -The electrode where reduction occurs.



What is a metallic pathway? - CORRECT ANSWER -The conductive path for electrons to flow.



What are electrolytes? - CORRECT ANSWER -
Substances that conduct electricity when dissolved in water.



What is the function of an electrolyte in corrosion? - CORRECT ANSWER -
Allows passage of ions in corrosion cell.



What is the function of a metallic pathway in corrosion? - CORRECT ANSWER -
Allows flow of electrons in corrosion cell.



What is the galvanic series? - CORRECT ANSWER -Listing of metals in order of reactivity.



What is the general rule of the galvanic series? - CORRECT ANSWER -
Less noble metal connected to a more noble metal will corrode preferentially.



What is localized corrosion? - CORRECT ANSWER -Corrosion that occurs in specific areas.



What are the types of localized corrosion? - CORRECT ANSWER -
Pitting and crevice corrosion.
