NACE CIP Level 1 Study Guide questions
and answers with solutions 2025
Define Corrosion - ANSWER The deterioration of a substance, usually a metal from a reaction
with its environment
What is passivation? - ANSWER A layer of oxides formed on the surface of a metal that provides
corrosion protection.
What is an example of passivation? - ANSWER Stainless Steel
What are the elements of a corrosion cell? - ANSWER Anode, Cathode, Metallic Pathway,
Electrolyte
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
The general rules of galvanic corrosion are: - ANSWER 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. - ANSWER Humidity,
oxygen, chemical salts, pollutants, temperature
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
Localized corrosion is: - 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.
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
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.
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.
Name some tests that may need to be conducted during surface preparation and coating
operations. - 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
