NACE CIP LEVEL 1 STUDY GUIDE LATEST ACTUAL EXAM WITH
VERIFIED QUESTIONS & CORRECT ANSWERS
Question 1.
Define Corrosion
Correct Answer: The deterioration of a substance, usually a metal from a
reaction with its environment
Question 2.
What is passivation?
Correct Answer: A layer of oxides formed on the surface of a metal that
provides corrosion protection.
Question 3.
What is an example of passivation?
Correct Answer: Stainless Steel
Question 4.
What are the elements of a corrosion cell?
Correct Answer: Anode, Cathode, Metallic Pathway, Electrolyte
Question 5.
Describe what happens at the anode.
Correct Answer: The metal dissolves into the electrolyte
Question 6.
What is the function of the electrolyte? Allows the passage of ions to connect the cor-
Correct Answer: rosion cell
Question 7.
What is the function of the metallic pathway?
Correct Answer: Allows the flow of electrons to connect the corrosion cell
Question 8.
What is the galvanic series?
Correct 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:
Correct Answer: The less noble (or more reactive) metal when connected to a
more noble (or less reactive metal) will corrode preferentially
Question 10.
Name the five most important factors that affect the rate of corrosion.
Correct Answer: Humidity, oxygen, chemical salts, pollutants, temperature
Question 11.
General corrosion is:
Correct 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:
Correct Answer: Typically pitting and crevice corrosion. It is typically of the
most concern 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.
Correct 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?
Correct 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?
Correct 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.
