NACE CIP LEVEL 1 STUDY GUIDE
QUESTIONS & DETAILED ANSWERS
PASSED ALREADY GRADED A+
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
