Describe what happens at the anode. - Answer: The metal dissolves into the electrolyte
What is the function of the electrolyte? - Answer: Allows the passage of ions to connect the corrosion
cell
What is the function of the metallic pathway? - Answer: Allows the flow of electrons to connect the
corrosion cell
What is the galvanic series? - Answer: A listing of metals in order of reactivity (more or less noble) in
seawater at 25 C

connected to a more noble (or less reactive metal) will corrode preferentially
Name the five most important factors that affect the rate of corrosion. - Answer: Humidity, oxygen,

Answer: Temperature, Relative Humidity, Dew Point, Anchor Profile, Surface Cleanliness
Name some of the documentation/reports that may be required to be maintained on a coatings project.
- Answer: Daily/weekly summary, material usage reports, manpower and equipment, non conformance,
and conformance
What are the most important characteristics of a good report? - Answer: Objective, Accurate, and
