About the program

What is the Professional Diploma in Corrosion Protection?

This professional diploma covers corrosion control as a complete engineering discipline. You will begin with the electrochemistry of corrosion, Pourbaix diagrams, polarization and Tafel curves, the main forms of corrosion including pitting, crevice, stress corrosion cracking and hydrogen embrittlement, and the measurement of corrosion rates. You will then study design and materials selection (carbon and stainless steels, duplex, non-ferrous alloys, polymers and FRP, galvanic isolation and life-cycle costing), environmental control with inhibitors, deaeration, water chemistry and biocides against MIC, surface preparation to ISO 8501-1 and SSPC/NACE standards, coating systems to ISO 12944 including zinc-rich, polysiloxane, thermal spray and FBE, sacrificial anode and impressed current cathodic protection, and finally inspection, monitoring and risk-based integrity management.

What sets this diploma apart: a scientific foundation in electrochemistry that lets you understand why each protection method works; all lines of defense in one program, from design and materials to inhibitors, coatings and cathodic protection; real calculation work on protection current and anode mass; strong reference to international standards such as ISO 12944, ISO 8501-1, ISO 21457 and NACE/AMPP; and a final project in which you develop a complete corrosion prevention and control plan for a ship or plant.

Frequently asked questions

Questions about the Professional Diploma in Corrosion Protection

To prevent or slow the deterioration of materials caused by corrosion, so that ships, structures and equipment remain safe and last longer at a lower maintenance cost.

No. It applies to ships and offshore structures, but also to pipelines, tanks, plants and other infrastructure exposed to aggressive environments.

Yes. You will calculate protection current requirements and anode mass for sacrificial systems and study the design, monitoring and maintenance of impressed current systems.

Among others ISO 12944 for paint systems, ISO 8501-1 and SSPC/NACE surface preparation grades, ISO 21457 and NACE/AMPP MR0175 for materials selection and the main cathodic protection criteria.

The diploma teaches the technical content behind those roles. Personal inspector certifications are issued separately by the relevant certification bodies.

It is fully online, with live and recorded classes, materials available at any time and personalized tutoring.

Through case studies, calculations, coating failure analyses, inspection exercises and a final project in which you develop a corrosion prevention and control plan for a plant or ship.
