Subject details

At the completion of this subject students will be able to:

  1. articulate fundamentals of cathodic protection (CP) and coating design and compare international specifications for different applications
  2. exemplify, predict, and recommend solutions to prevent stray current corrosion and alternating current (AC) interference associated with cathodic protection (CP)
  3. identify suitable types of coatings and applications for different environments
  4. explain and interpret synergistic relationships of coatings when used in conjunction with cathodic protection (CP).

Entry Requirements

You must have successfully completed the following subject(s) before starting this subject:

CUR-ENR500-Principles of Corrosion

Special requirements

No special requirements

This subject introduces students to the fundamentals of corrosion prevention by cathodic protection and coatings. This includes theoretical knowledge of various types of cathodic protection (CP) systems, their principles, applications, and limitations. Further, causes and effects of stray current and alternating current (AC) interference associated with CP will be discussed. Students will also learn about key coating selection criteria and techniques and instrumentation for coating inspection. Students will discover and identify any synergistic relationships between CP and coating.

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.
