NACE CIP Level 1 Study Guide Questions with Verified Answers
(Correct Update)
Question 1: Define Corrosion
Answer: The deterioration of a substance, usually a metal from a reaction with its environment
Question 2: What is Passivation?
Answer: A layer of oxides formed on the surface of a metal that provides corrosion protection.
Question 3: What is an example of passivation?
Answer: Stainless Steel
Question 4: What are the elements of a corrosion cell?
Answer: Anode, Cathode, Metallic Pathway, Electrolyte
Question 5: Describe what happens at the anode.
Answer: The metal dissolves into the electrolyte
Question 6: What is the function of the electrolyte?
Answer: Allows the passage of ions to connect the corrosion cell
Question 7: What is the function of the metallic pathway?
Answer: Allows the flow of electrons to connect the corrosion cell
Question 8: What is the galvanic series?
Answer: A listing of metals in order of reactivity (more or less noble) in seawater at 25 C
Question 9: The general rules of galvanic corrosion are:
Answer: The more reactive metal --when connected to the less reactive (more noble) metal -- will
corrode preferentially
Question 10: Name the five (5) most important factors that affect the rate of corrosion.
Answer: Humidity, oxygen, chemical salts, pollutants, temperature

, Question 11: General corrosion is:
Answer: Results in a relatively uniform loss of material over the entire surface, Results in a general
thinning of the affected surface, Relatively easy to inspect, Does not casue catastrophic failures
Question 12: Localized corrosion is:
Answer: At discrete/specific spots on the metal surface. Typically pitting and crevice corrosion. The
most concerning as damage is concentrated and loss of integrity or structural failure can result.
Question 13: List some of the common tools/methods used for corrosion control.
Answer: Design, Inhibitors, Material Selection, Cathodic Protection, Protective Coatings, Splash Zone
Systems, Alteration of the Environment
Question 14: How does NACE define the Inspector's role?
Answer: The inspector's role is that of a quality control technician responsible for observing and
reporting conformance or deviation from the project specification.
Question 15: What is the inspector's responsibility when it comes to safety on the project?
Answer: Safety enforcement is not the responsibility of the inspector; however, it is his/her
responsibility to report any issues that may affect the project.
Question 16: Name some tests that may need to be conducted during surface preparation and
coating operations.
Answer: Ambient Temperature, Relative Humidity & Dew Point, Anchor Profile, Surface Cleanliness
Question 17: 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, conformance, and
Non-conformance
Question 18: What are the most important characteristics of a good report?
Answer: Objective, Accurate, and Detailed.
