NACE CP1 EXAM WITH ALL CORRECT & 100%
VERIFIED ANSWERS|ALREADY GRADED A+
The deterioration of a substance, usually a metal from a reaction with its environment ✔Correct Answer-
corrosion
A layer of oxides formed on the surface of a metal that provides corrosion protection. ✔Correct Answer-
Passivation
Anode, cathode, metallic pathway, electrolyte ✔Correct Answer-the elements of a corrosion cell
The metal dissolves into the electrolyte ✔Correct Answer-what happens at the anode
Allows the flow of electrons to connect the corrosion cell ✔Correct Answer-the function of the metallic
pathway
A listing in order of reactivity ( more or less noble) in seawater 25c ✔Correct Answer-galvanic series
The less noble (more reactive) metal when connected to a more noble (or less reactive metal) will corrode
preferentially. ✔Correct Answer-The general rules of galvanic corrosion
Humidity, oxygen, chemical salts, pollutants, temperature ✔Correct Answer-the five most important factors
that affect the rate of corrosion.
Results in a relatively uniform loss of material over the entire surface. Results in a general thinning of the
affected surface. Realively easy to inspect. Does not cause catastrophic failures. ✔Correct Answer-General
corrosion
Typically pitting and crevice corrosion. It is typically of the most concern as damage is concentrated and loss of
integrity or structure failure can result. ✔Correct Answer-Localized corrosion
Design, inhibitors, material selection, cathodic protection, protective coatings, splash zone systems, alteration
of the environment ✔Correct Answer-Common tool/ methods used for corrosion control.
The electrode of an electrochemical cell at which oxidation occurs. Electrons flow away from the anode in the
external circuit. Corrosion usually occurs and metal ions enter the solution at the anode. ✔Correct Answer-
Anode
The electrode of an electrochemical cell at which reduction is the principal reaction. electrons flow towards the
cathode in the external circuit. ✔Correct Answer-Cathode
A technique to reduce the corrosion of a metal surface by making that surface the cathode of an
electrochemical cell. ✔Correct Answer-Cathodic protection
In order for corrosion to occur, certain conditions and elements are essential. This is the combination of an
anode, cathode, return path, and electrolyte. ✔Correct Answer-Corrosion cell
A chemical substance or combination of substances that, when present in the environment, prevents or reduces
corrosion ✔Correct Answer-Corrosion inhibitor
