It has already been established that iron aluminide coatings (Fe3Al) can increase the resistance to corrosion,oxidation and abrasion of materials. Application in the field of energy production are actively considered. Forexample as coating on turbo-generators of hydro-electric power plants. A desirable characteristic of thesecoatings is that they should be impermeable to hydrogen. Indeed, the presence of hydrogen in steel causes theembrittlement and loss of mechanical properties. In this project we will study the impact of hydrogen uptake onthe wear resistance of iron aluminide coatings on stainless steel. The influence of the intrinsic characteristics ofcoatings (crystalline structure, chemical composition, thickness, etc.) and extrinsic characteristics (hydrogenpressure, temperature, pH, etc.) on hydrogen uptake and wear resistance properties will be studied. This studywill be done in partnership with the Institute of Hydro-Québec Research at Varennes (IREQ) and WEIRCanada.

它已经是铝制涂层（FE3AL）可以在能量生产领域增加对矫正性的阻力，因为它是在水力发电厂的涡轮增压器上的涂层。 。与研究的研究将与瓦伦斯（IREQ）和Weircanada的Hydro-Québec研究所合作进行研究。
