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.

氢是未来能源的清洁燃料。它的生产和使用不可避免地涉及高温下的水蒸气和氢气，然而这会腐蚀系统中使用的材料。该项目旨在研究耐热合金在氢气和水蒸气存在下的腐蚀行为、氧化皮中水的传输机制以及氢气对水蒸气腐蚀的影响。将定义合金对腐蚀速率的影响，并设计在氢存在下减缓或防止水蒸气腐蚀的方法。研究结果将为制氢和氢利用行业耐热合金的改进设计/选择提供依据。
