PROTECTIVE COATING SPECIALIST (PCS) EXAM — 300 RANDOMIZED QUESTIONS
Exam Coverage Summary: The AMPP Protective Coating Specialist (PCS) certification exam
evaluates advanced knowledge of protective coatings for corrosion control. Topics include
corrosion theory and prevention, surface preparation standards (SSPC/NACE/ISO), coating types
and selection, application methods, inspection techniques and instrumentation, coating failure
analysis, safety and environmental regulations, project management and specification writing,
and quality assurance/quality control (QA/QC) procedures.
SECTION 1: CORROSION THEORY & FUNDAMENTALS (Questions 1-50)
1. Which of the following is NOT a required component for electrochemical corrosion to occur?
A) Anode
B) Cathode
C) Electrolyte
D) Oxygen
Answer: D
1

,Page 2 of 195
Oxygen is common but not required for all corrosion (e.g., anaerobic corrosion). The essential
components are anode, cathode, electrolyte, and metallic path.
2. What is the primary function of a protective coating?
A) Enhance color
B) Provide a decorative finish
C) Protect a substrate from corrosion and environmental degradation
D) Reduce surface friction
Answer: C
While aesthetics can be secondary, the core role of a protective coating is to isolate the
substrate (e.g., steel, concrete) from corrosive agents like oxygen, moisture, and chemicals,
thereby preventing corrosion or degradation.
3. What is galvanic corrosion?
A) Corrosion caused by acidic environments
B) Accelerated corrosion that occurs when two dissimilar metals are in electrical contact in the

presence of an electrolyte
C) Corrosion caused by high temperatures
D) Corrosion caused by biological organisms
Answer: B
Galvanic corrosion occurs when two dissimilar metals are electrically connected in an
electrolyte, causing the more anodic metal to corrode preferentially. The driving force is the
potential difference between the two metals.
4. What is the primary purpose of a primer in a coating system?
A) To provide aesthetic color
B) To act as a temporary protective layer
C) To improve adhesion and corrosion resistance
D) To reduce surface roughness
Answer: C
Primers improve coating adhesion to the substrate and provide corrosion resistance. They are
the first line of defense against corrosion.

5. What is the term for corrosion that occurs uniformly across a metal surface?
A) Pitting corrosion
B) Galvanic corrosion
C) General corrosion
D) Crevice corrosion
Answer: C
General corrosion is the relatively uniform attack over the exposed surface of a metal. It is the
most common type of corrosion and is typically less damaging than localized forms like pitting.
6. What is pitting corrosion?
A) Uniform metal loss across a surface
B) Localized corrosion that creates small pits or holes in the metal
C) Corrosion caused by dissimilar metals
D) Corrosion caused by high-velocity fluids
Answer: B
