5. Cathode
Answer:
Electrons flow towards the of an electrochemical cell.
Question:
6. Cathodic Protection
Answer:
A technique to reduce the corrosion of a metal surface by making that
surface the cathode of an electrochemical cell.
,Question:
7. Corrosion
Answer:
The deterioration of a material, usually a metal, that results from a reaction
with the environment.
Question:
8. Corrosion Cell
Answer:
In order for corrosion to occur, certain conditions and elements are essen-
tial. This combination of an anode, cathode, return path and electrolyte.
Question:
9. Crevice Corrosion
Answer:
Localized corrosion of a metal surface at, or immediately adjacent to, an
area that is shielded from full exposure to the environment because of
close proximity of the metal surface of another material.
Question:
10. Corrosion Inhibitor
Answer:
A chemical substance or combination of substances that, when present in
the environment, prevents or reduces corrosion.
Question:
11. Electrolyte
Answer:
A chemical substance containing ions that migrate in the electric field.
Question:
12. Galvanic Series
Answer:
A list of metals and alloys arranged according to their corrosion potentials
in a given environment.
,Question:
13. Generalized Corrosion Corrosion that is distributed more or less uniformly over the surface of a
Answer:
material.
Question:
14. Localized Corrosion
Answer:
This occurs at discrete sites on the metal surface.
Question:
15. Mill Scale
Answer:
The oxide layer formed during hot fabrication or heat treatment of metals.
Question:
16. Passivation
Answer:
A reduction of the anodic reaction rate of an electrode involved in corro-
sion.
Question:
17. 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:
18. Return Path (Metallic
Pathway)
Answer:
This connects the anode and cathode, allowing passage of electrons,
generated at the anode, to the cathode.

Answer:
ements of a corrosion
cell?
Question:
21. 1 - 2 - Describe what The part that corrodes, dissolves in electrolytes, dissolves in the form of
Answer:
happens at the anode positively charges ions, electrons generated are conducted to the cathode
Question:
22. 1 - 2 - What is the func- to conduct ionic current, closes the loop in the corrosion cell,
tion of the electrolyte?
Answer:
Question:
23. 1 - 2 - What is the
function of the metal-
lic pathway?
Answer:
to connect the anode to the cathode and allow passage of electrons.
Question:
24. 1 - 2 - What is the gal- a list of materials in order of their corrosion potentials, with the most easily
vanic series?
Answer:
corroded, or most active, at the top and the least active or corroded at the
bottom.
