NACE CIP 1 EXAM Practice Questions with Correct
Answers Latest 2023 | 2024 (Graded)
Anode
the electrode at which oxidation occurs.
electrons flow away from the the anode in the external circuit.
corrosion usually occurs and metal ions enter the solution at the anode
cathode
the electrode at which reduction occurs. electrons flow towards the cathode in the
external ciruit
cathodic protection
A technique to reduce the corrosion of a metal surface by making that surface the
cathode of an electrochemical cell.
corrosion
the deterioration of a material, usually a metal, that results from a reaction with its
environment.
corrosion inhibitor
A chemical substance or combination of substances that, when present in the
environment, prevents or reduces corrosion.
crevice corrosion
localized corrosion of a metal surface at, or immediately adjacent to, an area that is
shielded from the environment and full exposure due to the close proximity of the metal
to another surface
electrolyte
A chemical substance that promotes conduction of an electrical current
galvanic series
List of metals and alloys arranged according to their corrosion potentials in a given
environment (in sea water at 25 celcius)
generalized corrosion
Corrosion that is distributed more or less uniformly over the surface of a material
localized corrosion
Occurs at discrete sites and often in areas that are difficult to inspect
mill scale
The oxide layer formed during hot fabrication or heat treatment of metals.
Passivation
a layer of oxides formed on the surface of a metal that provides corrosion protection (ex
stainless steel)
a reduction of the anodic reaction rate of an electrode involved in corrosion,
Pitting Corrosion
Localized corrosion of a metal surface that is confined to a small area and takes the
form of cavities called pits.
Return Path (Metallic Pathway)
,Connects the anode and cathode, allowing passage of electrons, generated at the
anode, to the cathode
what are the elements of a corrosion cell
1. Anode 2. Cathode 3. Metallic pathway 4. Electrolyte
what happens at anode
oxidation. metal dissolves into electrolyte
what is the function of the electrolyte
Allows the passage of ions to connect the corrosion cell
what is the function of the metallic pathway
Allows the flow of electrons to connect the corrosion cell
The general rules of galvanic corrosion are:
The less noble (or more reactive) metal when connected to a more noble (or less
reactive metal) will corrode preferentially
name at least 5 factors that affect the rate of corrosion
temp, humidity, chemical salts, oxygen, pollutants
General Corrosion
Uniform loss of material over an entire surface and general thinning of affected surface
corrosion that is distributed more or less uniformly
does not cause catastrophic failures
Localized Corrosion
Occurs at discrete sites and often in areas that are difficult to inspect.
concentrated and can cause catastrophic failures
what are some of the common tools/methods used for corrosion control
inhibitors, design, cathodic protection, protective coatings, splash zone systems,
altering the environment
Coatings Specification
Formal, structured document containing information on a project (scope, terms,
schedule, inspection, etc.)
Instrument Calibration History Reports
Reports that normally contain information on how frequently each instrument is to be or
has been calibrated.
Materials Inventory Reports
Reports that contain information on the inventory of jobsite materials, and are normally
submitted periodically
safety data sheets (SDS sheets)
a form containing data of known substances in a particular product
Quality insurance (QA)
any systematic process that checks whether a manufactured product or service being
developed is meeting specified requirements
quality control (QC)
Procedure intended to ensure that a manufactured product or performed service meets
the requirements of the client or customer
quality control technician
, Inspector's role, primarily responsible for observing and reporting the technical aspects
of a coating project and its conformance or deviation from the project specifications
standards
a term applied to codes, specs, recommended practices, procedures, classifications,
test methods, and guides that provide interchangability and compatability.
enhance quality, safety, and economy. published by a standards development group of
organization
How does NACE define the inspector's role?
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 inspectors responsibility when it comes to safety on a project?
safety enforcement is NOT the role of the inspector. However, the inspector is
responsible to report any issues that may affect the project
Name some tests that may need to be conducted during surface preparation and
coating operations.
surface temp, 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.
daily reports, weekly summary, materials usage reports, manpower and equipment,
Non-conformance and conformance reports
what the the most important characteristics of a good report
accurate, detailed, objective
what is the inspectors primary responsibility and what should he/she not do as it
pertains to the specs
inspectors role is to ENFORCE specs only. inspector should NOT make any changes to
specs
what type of information could you expect to find on a product data sheet
surface prep and application info, such as recommended surface cleanliness,
application methods, and equipment sizes.
also environmental parameters like max and min application temps, curing times, recoat
windows
what type of information could you expect to find on sds sheets
health, safety, environmental.
necessary PPE.
physical characteristics
emergency responder info
dew point
The temperature at which condensation begins to form on a steel surface
Infrared thermometer
devices that measure temp, using blackbody radiation emitted from objects
Magnetic Surface Contact Thermometer
One of the most common instruments used to determine substrate temps.
