NACE CIP Level 1 Exam Questions and
Correct Answers
what's a coating? - Answer-a liquid, liquefiable, or mastic (thick film) composition that, after application
to a surface, is converted into a solid, protective, decorative, or functional adherent film.
What's the primary purpose for applying industrial coating? - Answer-to prevent or limit contact
between a metal substrate and its corrosive environment. (In order for the coating tube able to protect
against corrosion.)
What is paint used for? - Answer-aesthetic or decorative purpose
What is coating used for? - Answer-for performance or protective purposes
Four reasons for coatings in industrial environments - Answer-Aesthetics
Performance requirements
Safety identification
Corrosion prevention and control
, What's corrosion? - Answer-the deterioration of a metal or alloy that results from an electrochemical
reaction with its environment.
Anode - Answer-The area of the metal surface that corrodes.
The metal oxidizes(gains oxygen) causing it to lose mass and dissolve into the electrolyte. The metal that
dissolves does so in the form of positively charged cations that then migrate to the cathode through the
electrolyte.
Oxidation - Answer-A chemical reaction that occurs at the anode where the metal losses electrons.
Cathode - Answer-The area of the metal surface that reduces (loses oxygen), does not corrode and is
protected. The metal forms negatively charged anions that migrate to the anode through the
electrolyte. Electrons flow from the anode toward the cathode in the metallic pathway.
Reduction - Answer-A chemical reaction that occurs at the cathode that involves the gain of electrons to
the metal. Reduction and oxidation always occur together through an exchange of electrons at specific
sites on the metal surface
Metallic pathway - Answer-Connects the anode and cathode and allows the passage of electrons
generated at the anode to the cathode. The metallic pathway is often the underlying metal substrate
Electrolyte - Answer-A conductive medium in which ions are carried from the anode to the cathode. The
electrolyte is any solution capable of conducting electricity, such as water.
Cathodic protection - Answer-adds a sacrificial metal or anode to a system that then corrodes instead of
the core asset.
Oxygen - Answer-increases the rate of corrosion. Corrosion can take place in an oxygen-deficient
environment, but the rate of the corrosion reaction is generally much slower
