Study of the effect of hydrogen in iron aluminide coatings on the tribological behavior

铝化铁涂层（Fe3Al）可以提高材料的抗腐蚀、抗氧化和抗磨损性能。积极考虑在能源生产领域的应用。例如，水电厂涡轮发电机的涂层。这些涂层的一个理想特性是它们应该不渗透氢。事实上，钢中氢的存在导致了钢的脆化和机械性能的损失。在这个项目中，我们将研究吸氢对不锈钢铝化铁涂层耐磨性的影响。研究涂层的内在特性（晶体结构、化学成分、厚度等）和外在特性（氢压力、温度、pH等）对吸氢性能和耐磨性的影响。这项研究**将与Varennes hydro - qusambec研究所（IREQ）和加拿大WEIR**合作完成。

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. For**example as coating on turbo-generators of hydro-electric power plants. A desirable characteristic of these**coatings is that they should be impermeable to hydrogen. Indeed, the presence of hydrogen in steel causes the**embrittlement and loss of mechanical properties. In this project we will study the impact of hydrogen uptake on**the wear resistance of iron aluminide coatings on stainless steel. The influence of the intrinsic characteristics of**coatings (crystalline structure, chemical composition, thickness, etc.) and extrinsic characteristics (hydrogen**pressure, temperature, pH, etc.) on hydrogen uptake and wear resistance properties will be studied. This study**will be done in partnership with the Institute of Hydro-Québec Research at Varennes (IREQ) and WEIR**Canada.
