The beneficial effect of yttrium addition on the oxidation behaviour of the 304 stainless steel, under isothermal conditions at 1000 o C in air, has been investigated. Two modes of introduction of the reactive element were studied, ion implantation and sol-gel coating. The thermogravimetric results show in both cases a significant reduction of the scale growth rate. In situ X-ray diffraction...
High-temperature alloys are frequently used in power plants, gasification systems, petrochemical industry, combustion processes and in aerospace applications. Depending on the application, materials are subjected to corrosive atmospheres and thermal cycling. In the present work, thermal cycling was carried out in order to study the influence of implanted yttrium on the oxide scale adherence on 304...
