NACE (NATIONAL ASSOCIATION OF
CORROSION ENGINEERS) CIP 1 EXAM
STUDY KIT WITH COMPLETE QUESTIONS
AND CORRECT ANSWERS GRADED A+
Anode Correct Answer 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 Correct Answer the electrode at which reduction occurs.
electrons flow towards the cathode in the external ciruit
cathodic protection Correct Answer A technique to reduce the
corrosion of a metal surface by making that surface the cathode
of an electrochemical cell.
corrosion Correct Answer the deterioration of a material, usually
a metal, that results from a reaction with its environment.
corrosion inhibitor Correct Answer A chemical substance or
combination of substances that, when present in the environment,
prevents or reduces corrosion.
crevice corrosion Correct Answer 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 Correct Answer A chemical substance that promotes
conduction of an electrical current
,galvanic series Correct Answer List of metals and alloys
arranged according to their corrosion potentials in a given
environment (in sea water at 25 celcius)
generalized corrosion Correct Answer Corrosion that is
distributed more or less uniformly over the surface of a material
localized corrosion Correct Answer Occurs at discrete sites and
often in areas that are difficult to inspect
mill scale Correct Answer The oxide layer formed during hot
fabrication or heat treatment of metals.
Passivation Correct Answer 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 Correct Answer 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) Correct Answer Connects the
anode and cathode, allowing passage of electrons, generated at
the anode, to the cathode
what are the elements of a corrosion cell Correct Answer 1.
Anode 2. Cathode 3. Metallic pathway 4. Electrolyte
what happens at anode Correct Answer oxidation. metal
dissolves into 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
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 at least 5 factors that affect the rate of corrosion Correct
Answer temp, humidity, chemical salts, oxygen, pollutants
General Corrosion Correct Answer 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 Correct Answer 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 Correct Answer inhibitors, design, cathodic protection,
protective coatings, splash zone systems, altering the
environment
Coatings Specification Correct Answer Formal, structured
document containing information on a project (scope, terms,
schedule, inspection, etc.)
