Overview

This unit introduces the fundamental science underlying various corrosion phenomena, using both lectures and laboratory sessions. 

Aims

To introduce the thermodynamic and kinetic principles of the chemical and electrochemical processes that give rise to both aqueous corrosion in electrolytes, • To high temperature oxidation in gases. • To enable students to understand the experimental techniques for measuring and monitoring corrosion rates • To give students hand on experience of operating potentiostatic equipment to conduct investigations into corrosion.

Learning outcomes

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

Lectures, group tutorials (problem sessions), recommended textbooks, web resources, self- teaching worked examples, past exam papers, electronic supporting information (Blackboard).

 

Knowledge and understanding

Understand the common mass transport mechanisms in solutions; use Fick's laws to solve diffusion problems.

Describe the central role of dislocation motion in controlling the properties of metals including explaining phenomena such as work hardening.

Understand the chemistry of typical aqueous solutions in which corrosion could occur, such as salts, acids and alkalis, and be able to describe how the solution chemistry will affect the rate and type of corrosion expected for common metals such as iron, copper and aluminium.

Discuss how the Tafel Law predicts current density for activation controlled processes.

Recognise when mass transport will limit different interfacial processes and predict the effect on the corrosion potential and corrosion current density.

Explain the stages of high temperature oxidation and the kinetics for different types of oxides.

Understand the theory for Electrochemical Impedance Spectroscopy. 

Intellectual skills

Explain how to relate corrosion current densities to corrosion rates using Faraday’s Law.

Interpret a polarisation curve to determine the types of interfacial processes occurring.

Measure the gradient of the appropriate part of a Linear Polarisation Curve to find the Polarisation Resistance.

Perform calculation using Fick’s Laws to predict corrosion rates for cases diffusion limited reactions are rate limiting.

Use a Pourbaix diagram to describe the surface state for a metal in a known solution.

Measure corrosion rates from the results of impedance measurements. 

Practical skills

Perform experiments to measure corrosion rates in aqueous environments.

Use a potentiostat correctly with either two or three electrode setups. 

Transferable skills and personal qualities

Gain experience of working in a group to produce coursework.
