Abstract

The practical use of FeAl intermetallic alloys will be possible in a wider range after the development of not only the technology of making permanent joints, but also after determining their physicochemical properties. In the work, the surface condition of the intermetallic FeAl alloy by use TIG AC and DC(-) were remelted and in the air at 900 and 1000 °C were oxidized. Differences in the surface state of melted Fe40Al5Cr0.2TiB alloy were found depending on its area, in particular in the area of remelting and fusion line. For the tests, the Fe40Al5Cr0.2TiB intermetallic alloy was used as the basic material after casting, which was modified by TIG remelting. Next, microstructure analysis was performed using light microscopy, scanning electron microscopy and hardness measurements before and after oxidation. In addition, corrosion products were analyzed using XRD.
