About the course

The cost of industrial corrosion is estimated to be more than $2 trillion per year globally (NACE study). There have also been several major failures and industrial incidents within the Refining, Chemical & Power Generation sectors. It is important that key staff working within these industries have a fundamental appreciation of corrosion types: their threats, diagnosis, and mitigation.

This self-paced learning path will introduce students to the material degradation, corrosion, and cracking mechanisms found within the refining, chemical, and power-generation sectors. The learning path breaks these mechanism types down into 8 main courses. Each of these modules explains the scientific principles involved and shows real-world examples. Industrial safety incident videos are also presented and the lessons to be learned from each of these are discussed by the instructor.

This introductory learning path to corrosion contains 8 online courses, which in total are 13 hours of video content. All training content is provided through your EngineeringTrainer account.
