NACE CIP Level 1 Study Guide UPDATED ACTUAL Questions and
CORRECT Answers
1. Define Corrosion The deterioration of a substance, usually a met-
al from a reaction with its environment
2. What is passivation? A layer of oxides formed on the surface of a
metal that provides corrosion protection.
3. What is an example of passivation? Stainless Steel
4. What are the elements of a corrosion Anode, Cathode, Metallic Pathway, Electrolyte
cell?
5. Describe what happens at the anode. The metal dissolves into the electrolyte
6. What is the function of the electrolyte? Allows the passage of ions to connect the cor-
rosion cell
7. What is the function of the metallic path- Allows the flow of electrons to connect the cor-
way? rosion cell
8. What is the galvanic series? A listing of metals in order of reactivity (more or
less noble) in seawater at 25 C
9. The general rules of galvanic corrosion The less noble (or more reactive) metal when
are: connected to a more noble (or less reactive
metal) will corrode preferentially
10. Name the five most important factors Humidity, oxygen, chemical salts, pollutants,
that affect the rate of corrosion. temperature
11. General corrosion is: 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
, 12. Localized corrosion is: Typically pitting and crevice corrosion. It is typi-
cally of the most concern as damage is concen-
trated and loss of integrity or structural failure
can result.
13. List some of the common tools/meth- Design, Inhibitors, Material Selection, Cathod-
ods used for corrosion control. ic Protection, Protective Coatings, Splash Zone
Systems, Alteration of the Environment
14. How does NACE define the inspector's The inspector's role is that of a quality con-
role? trol technician responsible for observing and
reporting conformance or deviation from the
project specification.
15. What is the inspector's responsibility Safety enforcement is not the responsibility of
when it comes to safety on the project? the inspector; however, it is his/her responsi-
bility to report any issues that may affect the
project.
16. Name some tests that may need to be Temperature, Relative Humidity, Dew Point, An-
conducted during surface preparation chor Profile, Surface Cleanliness
and coating operations.
17. Name some of the documentation/re- Daily/weekly summary, material usage reports,
ports that may be required to be main- manpower and equipment, non conformance,
tained on a coatings project. and conformance
18. What are the most important character- Objective, Accurate, and Detailed.
istics of a good report?
19. What is the inspector's primary respon- The Inspector's primary responsibility as the
sibility and what should the inspector inspector is to "enforce" specification. The in-
not do as it pertains to the specification.
