NACE CIP Level 1 Study Guide Questions With All Correct
Answers
Define Corrosion correct answer -The deterioration of a substance, usually
a metal from a reaction with its environment
What is passivation? correct answer -A layer of oxides formed on the
surface of a metal that provides corrosion protection.
What is an example of passivation? correct answer -Stainless Steel
What are the elements of a corrosion cell? correct answer -Anode,
Cathode, Metallic Pathway, Electrolyte
Describe what happens at the anode. correct answer -The metal dissolves
into the electrolyte
What is the function of the electrolyte? correct answer -Allows the passage
of ions to connect the corrosion cell
What is the function of the metallic pathway? correct answer -Allows the
flow of electrons to connect the corrosion cell
What is the galvanic series? correct 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: correct 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.
correct answer -Humidity, oxygen, chemical salts, pollutants, temperature
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
, 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.
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
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.
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.
Name some tests that may need to be conducted during surface preparation
and coating operations. correct 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. correct answer -Daily/weekly summary,
material usage reports, manpower and equipment, non conformance, and
conformance
What are the most important characteristics of a good report? correct
answer -Objective, Accurate, and Detailed.
What is the inspector's primary responsibility and what should the inspector
not do as it pertains to the specification. correct answer -The Inspector's
primary responsibility as the inspector is to "enforce" specification. The
inspector is NOT to make changes to the specification for any reason.
What type of information could you expect to find on a Product Data Sheet?
correct answer -Surface preparation and application information such as
recommended level of surface cleanliness, recommended application methods
