At the completion of this subject students will be able to:
- recognise the advantages, disadvantages, and limitations of corrosion prevention by conversion, organic, metallic, and inorganic coatings.
- select appropriate coatings for different corrosion scenarios.
- identify key requirements regarding surface preparation, coating application, and inspection. Identify common defects on organic, metallic, and inorganic coatings, including coating degradation during exposure.
- describe the fundamentals of anodic and cathodic protection, comparing various international standards and design codes —Includes the combination of cathodic protection and coatings.
- make simple anodic and cathodic protection design calculations, identifying solutions to common issues such as shielding, coating disbondment, and stray current and AC interference.
- explain the various monitoring and inspection methods for both anodic and cathodic protection as well as common modeling tools.

No special requirements
This subject was previously known as Cathodic Protection and Coating.
This subject introduces students to the fundamentals of corrosion prevention by conversion, organic, metallic, and inorganic coatings as well as electrochemical protection. Topics cover both fundamental and applied aspects of coating technologies and anodic and cathodic protection, their principles, applications, and limitations. Students will also learn about organic and metallic coating application methods, inspection strategies, and identification of characteristic defects. By the end of the subject, students should be able to select coatings for different case studies as well as performing simple anodic and cathodic protection calculations.
Please Note: If it’s your first time studying a Curtin University subject you’ll need to complete their compulsory ‘Academic Integrity Program’. It only takes two hours to complete online, and provides you with vital information about studying with Curtin University. The Academic Integrity Program is compulsory, so if it’s not completed your subject grades will be withheld.
