AMPP Senior Corrosion Technologist study guide
AMPP Senior Corrosion Technologist · Work through your exam, one topic at a time.
The Senior Corrosion Technologist (SCT) certification is an AMPP credential for experienced corrosion professionals who need to demonstrate broad technical expertise across corrosion prevention and control. AMPP states it is intended for metallurgists, design engineers, corrosion and equipment engineers, inspectors and inspection supervisors, maintenance and QA/QC personnel, and supervisors or foremen. The AMPP Senior Corrosion Technologist study guide has 6 sections and about 1,813 words.
01Metallurgy for the Corrosion Technologist
Corrosion is an electrochemical process, so metallurgy questions usually test how composition and microstructure change corrosion behavior. Be comfortable with the galvanic series (noble/cathodic vs.
345 words, about 2 min02Chemical Treatment and Corrosion Inhibitors
Chemical treatment covers water chemistry control, inhibitor selection, and the interaction between treatment and corrosion mechanism. Understand the three broad inhibitor classes: anodic (passivating, e.g., nitrite, molybdate, chromate historically), cathodic (e.g., zinc salts, polyphosphates that form films), and mixed/organic film-formers (amines, azoles for copper).
319 words, about 2 min03Coating Systems: Selection, Application, and Failure
Coatings are barrier and, for some systems, sacrificial or inhibitive protection. Know the components: resin/binder, pigment, solvent, and additives, and how each affects performance.
292 words, about 1 min04Internal Corrosion: Mechanisms and Control
Internal corrosion occurs in pipelines, vessels, and equipment where a fluid contacts metal. The candidate must understand the dominant mechanisms: CO2 (sweet) corrosion, H2S (sour) corrosion and sulfide stress cracking, oxygen corrosion, galvanic and crevice attack under deposits, erosion-corrosion from flow, and MIC.
289 words, about 1 min05Cathodic Protection: Principles and Practice
Cathodic protection (CP) makes the structure the cathode of a corrosion cell, polarizing it to a potential where anodic dissolution is suppressed. Know the two methods: galvanic (sacrificial anodes such as zinc, aluminum, magnesium) and impressed current (rectifier, inert anodes).
286 words, about 1 min06Safety Planning for Corrosion Work
Safety planning covers hazard identification, risk assessment, and safe work practices for corrosion inspection, coating, and CP work. Understand the hierarchy of controls: elimination, substitution, engineering controls, administrative controls, and PPE.
