CORROSION ENGINEERS) CIP LEVEL 1
STUDY GUIDE WITH COMPLETE
QUESTIONS AND CORRECT ANSWERS
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
Define Corrosion Correct Answer The deterioration of a
substance, usually a metal from a reaction with its environment
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
more reactive metal --when connected to the less reactive (more
noble) metal -- will corrode preferentially
,Name the five (5) 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 At discrete/specific spots
on the metal surface. Typically pitting and crevice corrosion. The
most concerning 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 Ambient
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, conformance, and Non-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 [Material]
Product Data Sheet (PDS)? Correct Answer Surface preparation
and application information such as recommended level of
surface cleanliness, recommended application methods and
equipment such as tip sizes. Also, environmental parameters for
application such as max and min temperatures, curing times,
recoat windows.
What type of information could you expect to find on a Safety
Data Sheet? Correct Answer Health, safety and environmental.
The PPE required. Physical characteristics. Emergency
responder information.
Explain the difference between Quality Assurance (QA) and
Quality Control (QC). Correct Answer Quality Assurance - Any
systematic process of checking to see whether a product or
service being developed is meeting specs.
*Quality Control* - A procedure or set of procedures intended to
ensure that a manufactured product or performed service adheres
, to a defined set of quality criteria or meets the requirements of the
client or customer
Identify some of the defects that can be caused by incorrect
application temperatures. Correct Answer Failure to cure, too
rapid solvent evaporation, poor film formation
Describe relative humidity. Correct Answer The amount of
moisture in the air compared to saturation level
What is the dew point temperature? Correct Answer The
temperature at which moisture will begin to form on a steel
surface.
Name some of the effects wind may have on a coatings project.
Correct Answer blowing abrasives, causing excessive drift or
overspray, accelerating solvent evaporation, contributing to the
formation of dry spray
What are some of the common errors when using an electronic
hygrometer? Correct Answer Failure to acclimate the instrument
to the environment with adequate time.
Explain the process for use of the sling psychrometer. Correct
Answer Make sure the wick is wet and clean, continue to "sling"
until 3 consecutive readings are achieved
List three (3) desirable properties of a coating? Correct Answer
Chemical Resistance, water resistance, ease of application,
cohesive strength, impact resistance, dielectric strength
Two broad classifications of a coating are: Correct Answer
Organic/Inorganic, Convertible/non-convertible,
thermosetting/thermoplastic
