Investigation and characterisation of corrosion mechanism for the sol-gel developed Cr6+ free coatings for aircraft Al or Mg alloys

The aim of this project is to optimise a Cr6+ free pretreatment primer.

Al and Mg alloys are widely used in aircraft industries. The ban of the Cr6+ contained coatings for the protection of these metals in aircraft industries are approaching. This project will add various corrosion inhibitors in the formulation to investigate their corrosion resistance and mechanism to the coated metal through electrochemical analysis. The adhesion, flexibility and other mechanical properties will be studied. Thickness, structures and morphologies of the coating will be characterised by SEM, IR and AFM.

Please contact Dr Nick Farmilo for further information.
