AMPP Corrosion Technician study guide
AMPP Corrosion Technician · Work through your exam, one topic at a time.
The AMPP Corrosion Technician Certification is an industry credential for people who perform routine corrosion-control work under the direction of more senior technologists. AMPP describes it as designed for professionals with foundational experience who want industry-recognized validation of practical knowledge. Eligibility requires two years of verifiable corrosion-related work experience plus successful completion of the Ethics for the Corrosion Professional course or equivalent training; one pathway additionally requires the Basic Corrosion Course and Corrosion Foundations Micro-Credential. Candidates in that pathway are not required to take an additional exam, while the experience-only pathway requires the Corrosion Technician Certification Exam. The AMPP Corrosion Technician study guide has 5 sections and about 1,451 words.
01Cathodic Protection
Cathodic protection (CP) forces a buried or immersed metal to act as the cathode of an electrochemical cell, suppressing anodic dissolution. Two methods dominate: galvanic (sacrificial anodes such as magnesium, zinc, and aluminum alloys) and impressed current (a rectifier driving current through inert anodes like mixed metal oxide or graphite).
318 words, about 2 min02Protective Coatings
Protective coatings isolate metal from the electrolyte and are the primary defense against external and internal corrosion. A candidate should understand surface preparation, coating selection, application variables, and inspection.
280 words, about 1 min03Materials and Metallurgy
Materials selection determines whether a component corrodes, passivates, or fails mechanically. Candidates should understand galvanic series relationships, passivity, sensitization, and common alloy families.
298 words, about 1 min04Chemical Treatment (Inhibitors)
Corrosion inhibitors reduce corrosion by interfering with anodic, cathodic, or both reactions, or by forming a barrier film. Candidates should classify inhibitors (anodic, cathodic, mixed, and film-forming or adsorption types), understand dosage and application methods, and recognize when inhibitors are appropriate.
280 words, about 1 min05General Corrosion
General corrosion fundamentals underpin every other domain. Candidates must understand the electrochemical nature of corrosion: an anodic oxidation reaction releasing electrons, a cathodic reduction reaction consuming them, an electrolyte path, and a metallic return path.
