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 course will introduce students to the material degradation, corrosion, and cracking mechanisms found within the refining, chemical, and power-generation sectors. The course breaks these mechanism types down into 8 main modules. 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 course to corrosion contains 8 online modules, which in total are 13 hours of video content. All training content is provided through your EngineeringTrainer account.
