In this unit you will learn about how surface coatings and electrochemical methods can be used to manage and control the corrosion damage of structural materials in natural environments and how economic analysis, corrosion testing and the application of standards can help in determining the most appropriate and cost-effective corrosion control solution.
This unit studies the factors that influence the performance of materials used in vehicles, vessels and aircraft as well as materials in the built environment on land and offshore.
A greater depth of the learning outcomes will be covered in the following sections:
• Knowledge and understanding
• Intellectual skills
• Practical skills
• Transferable skills and personal qualities
Teaching and learning methods
Feedback given verbally and written.
Knowledge and understanding
Explain the factors that influence corrosion damage in the natural environments of the sea, the soil, lakes and rivers, and in the air (the atmospheric environment).
Recognise the key differences between natural and industrial environ-ments and how these mechanistically influence corrosion processes.
Summarise the main methods for corrosion control of structural materials.
Identify how corrosion testing and the application of industry standards can be used to select suitable corrosion control methods
Describe methods by which protective coatings may be applied to structural materials and how their service performance may be tested
Explain how anodising can improve the corrosion performance of light alloys and anodic passivation that of corrosion resistant alloys
Describe the industrial application of cathodic protection giving examples; explain how calcareous films develop and evolve during cathodic protection.
Interpret thermodynamic (i.e. E v. pH or Pourbaix) and/or kinetic (i.e. E v log(i) or Evans’) diagrams to summarise how cathodic protection and anodic passivation work.
Employ the theory of high field ion conduction to illustrate the mechanism of anodic film formation on valve metals; recognise how pH and potential influence the formation of porous or barrier anodic films.
Appraise and justify the Nguyen and Mayne mechanisms for the corrosion protection by organic coatings; defend these ideas against competing theories.
Measure the effectiveness of cathodic protection by mapping the corrosion potential of a galvanically protected structure.
Transferable skills and personal qualities
Apply discounted cash flow analysis and life-cycle costing to analyse suitable corrosion control options for the protection of a steel bridge. Complete a presentation to justify the most suitable option to a non-technical audience.
Lectures, group tutorials (problem sessions), recommended textbooks, web resources, self- teaching worked examples, past exam papers, electronic supporting information (Blackboard).
