AMPP CIP LEVEL 1 ACTUAL TEST PAPER WITH COMPLETE ANSWERS
◍ 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.
