NACE CIP 1 Exam Questions with Verified Answers (Correct Update)
Question 1: 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
Question 2: cathode
Answer: the electrode at which reduction occurs. electrons flow towards the cathode in the external
ciruit
Question 3: cathodic protection
Answer: A technique to reduce the corrosion of a metal surface by making that surface the cathode of
an electrochemical cell.
Question 4: corrosion
Answer: the deterioration of a material, usually a metal, that results from a reaction with its
environment.
Question 5: corrosion inhibitor
Answer: A chemical substance or combination of substances that, when present in the environment,
prevents or reduces corrosion.
Question 6: crevice corrosion
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
Question 7: electrolyte
Answer: A chemical substance that promotes conduction of an electrical current
Question 8: galvanic series
Answer: List of metals and alloys arranged according to their corrosion potentials in a given
environment (in sea water at 25 celcius)

, Question 9: generalized corrosion
Answer: Corrosion that is distributed more or less uniformly over the surface of a material
Question 10: localized corrosion
Answer: Occurs at discrete sites and often in areas that are difficult to inspect
Question 11: mill scale
Answer: The oxide layer formed during hot fabrication or heat treatment of metals.
Question 12: 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,
Question 13: Pitting Corrosion
Answer: Localized corrosion of a metal surface that is confined to a small area and takes the form of
cavities called pits.
Question 14: Return Path (Metallic Pathway)
Answer: Connects the anode and cathode, allowing passage of electrons, generated at the anode, to the
cathode
Question 15: what are the elements of a corrosion cell
Answer: 1. Anode 2. Cathode 3. Metallic pathway 4. Electrolyte
Question 16: what happens at anode
Answer: oxidation. metal dissolves into electrolyte
Question 17: what is the function of the electrolyte
Answer: Allows the passage of ions to connect the corrosion cell
Question 18: what is the function of the metallic pathway
Answer: Allows the flow of electrons to connect the corrosion cell
