NACE CIP Study Guide Essential Questions
And Accurate Answers 2025\2026 A+ Grade
Define Corrosion
- accurate answers-The deterioration of a substance, usually a metal from a
reaction with its environment
What is passivation?
- accurate answers-A layer of oxides formed on the surface of a metal that
provides corrosion protection.
What is an example of passivation?
- accurate answers-Stainless Steel
What are the elements of a corrosion cell?
- accurate answers-Anode, Cathode, Metallic Pathway, Electrolyte
Describe what happens at the anode.
- accurate answers-The metal dissolves into the electrolyte
What is the function of the electrolyte?
- accurate answers-Allows the passage of ions to connect the corrosion cell
What is the function of the metallic pathway?
- accurate answers-Allows the flow of electrons to connect the corrosion cell
What is the galvanic series?
- accurate answers-A listing of metals in order of reactivity (more or less
noble) in seawater at 25 C
The general rules of galvanic corrosion are:
- accurate answers-The less noble (or more reactive) metal when connected
to a more noble (or less reactive metal) will corrode preferentially
Name the five most important factors that affect the rate of corrosion.
- accurate answers-Humidity, oxygen, chemical salts, pollutants, temperature
General corrosion is:
- accurate answers-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
Localized corrosion is:
- accurate answers-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.
List some of the common tools/methods used for corrosion control.
- accurate answers-Design, Inhibitors, Material Selection, Cathodic Protection,
Protective Coatings, Splash Zone Systems, Alteration of the Environment
How does NACE define the inspector's role?
- accurate answers-The inspector's role is that of a quality control technician
responsible for observing and reporting conformance or deviation from the
project specification.
What is the inspector's responsibility when it comes to safety on the project?
- accurate answers-Safety enforcement is not the responsibility of the
inspector; however, it is his/her responsibility to report any issues that may
affect the project.
Name some tests that may need to be conducted during surface preparation
and coating operations.
- accurate answers-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.
- accurate answers-Daily/weekly summary, material usage reports,
manpower and equipment, non conformance, and conformance
What are the most important characteristics of a good report?
- accurate answers-Objective, Accurate, and Detailed.
What is the inspector's primary responsibility and what should the inspector
not do as it pertains to the specification.
- accurate answers-The Inspector's primary responsibility as the inspector is
