NACE CIP Actual Questions and Correct Answers
Q1
Anode
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
Q2
cathode
Answer: the electrode at which reduction occurs. electrons flow towards the cathode
in the external ciruit
Q3
cathodic protection
Answer: A technique to reduce the corrosion of a metal surface by making that surface
the cathode of an electrochemical cell.
Q4
corrosion
Answer: the deterioration of a material, usually a metal, that results from a reaction
with its environment.
Q5
corrosion inhibitor
Answer: A chemical substance or combination of substances that, when present in the
environment, prevents or reduces corrosion.
Q6
crevice corrosion
Answer: localized corrosion of a metal surface at, orimmediately adjacent to, an area
that is shieldedfrom the environment and full exposure due to the close proximity of
the metal to another surface
, Q7
electrolyte
Answer: A chemical substance that promotes conduction of an electrical current
Q8
galvanic series
Answer: List of metals and alloys arranged according totheir corrosion potentials in a
given environment (in sea water at 25 celcius)
Q9
generalized corrosion
Answer: Corrosion that is distributed more or less uniformly over the surface of a
material
Q10
localized corrosion
Answer: Occurs at discrete sites and often in areas that are difficult to inspect
Q11
mill scale
Answer: The oxide layer formed during hot fabrication or heat treatment of metals.
Q12
Passivation
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,
Q13
Pitting Corrosion
Answer: Localized corrosion of a metal surface that is confined to a small area and
takes the form of cavities called pits.
