Project summary description:
Hydrogen is a clean fuel for energy future. Its production and utilisation unavoidably involve water vapour and hydrogen at high temperature, which is however corrosive to materials used in the system. This project aims to investigate corrosion behaviour of heat-resistant alloys in the presence of both hydrogen and water vapour, mechanisms of water transport in oxide scale, and the effect of hydrogen on water vapour corrosion. Alloying effects on corrosion rates will be defined and methods of slowing or preventing water vapour corrosion in the presence of hydrogen will be devised. The results will provide a basis for improved design/selection of heat resisting alloys for hydrogen production and hydrogen utilisation industries.
