Question:
1. Define Corrosion
Answer:
The deterioration of a substance, usually a met-
al from a reaction with its environment
Question:
2. What is passivation?
Answer:
A layer of oxides formed on the surface of a
metal that provides corrosion protection.
Question:
3. What is an example of passivation?
Answer:
Stainless Steel
Question:
4. What are the elements of a corrosion
cell?
Answer:
Anode, Cathode, Metallic Pathway, Electrolyte
Question:
5. Describe what happens at the anode.
Answer:
The metal dissolves into the electrolyte
Question:
6. What is the function of the electrolyte?
Answer:
Allows the passage of ions to connect the cor-
,rosion cell
Question:
7. What is the function of the metallic path- Allows the flow of electrons to connect the cor-
way?
Answer:
rosion cell
Question:
8. What is the galvanic series?
Answer:
A listing of metals in order of reactivity (more or
less noble) in seawater at 25 C
Question:
9. 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
Question:
10. Name the five most important factors
that affect the rate of corrosion.
Answer:
Humidity, oxygen, chemical salts, pollutants,
temperature
Question:
11. 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
, Question:
12. Localized corrosion is:
Answer:
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.
Question:
13. List some of the common tools/meth-
ods used for corrosion control.
Answer:
Design, Inhibitors, Material Selection, Cathod-
ic Protection, Protective Coatings, Splash Zone
Systems, Alteration of the Environment
Question:
14. How does NACE define the inspector's
role?
Answer:
The inspector's role is that of a quality con-
trol technician responsible for observing and
reporting conformance or deviation from the
project specification.
Question:
15. What is the inspector's responsibility Safety enforcement is not the responsibility of
Answer:
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.
Question:
16. Name some tests that may need to be
conducted during surface preparation
and coating operations.
