About the Project

AWE currently uses chromic acid anodising for passivating aluminium alloys to provide corrosion protection in a range of applications. Chromic acid anodising, however, gives rise to waste hexavalent chromium which is restricted under the European Union’s REACH Regulations. Alternative anodising treatments are therefore required.

This novel research programme is an evidence-based approach to develop anodised coatings that are fit for purpose in terms of key material properties, e.g. corrosion resistance, mechanical robustness, electrical breakdown voltage, coating adherence, and radiation hardness. The morphology and microstructure of the anodised layer will be analysed with various electron microscopy methods. Other techniques will be used to study the composition and surface chemistry of the coatings. The performance of the coatings will be assessed as a function of processing parameters, i.e. time, temperature, pH, and voltage. This experimental data will enable the coating performance to be related to the anodised layer’s microstructure and composition.

Your personal development is a priority for us during your doctorate. £1,000 per annum is available for training events and conference attendance. This is in addition to our Doctoral College’s researcher development programme and our annual centre conference. Plus our network of sponsors, who support our annual conference, help you find the next step after your doctorate.

Supervisors: Professor John F Watts, Dr Mark J Whiting.
