Microstructure and magnetic properties of atmospheric plasma sprayed Fe-40Al coating obtained from nanostructured powders

Abstract : Amorphous and nanocrystalline materials have attracted much interest in the field of new materials design because of their excellent mechanical and physical properties as well as their magnetic properties. In this work, Fe-40Al coatings were prepared from nanostructured feedstock with a very low degree of order using atmospheric plasma spraying. Scanning electron microscopy, X-ray diffraction, and magnetic measurements were used to investigate microstructure, phase structure, and magnetic properties of the coatings. The results showed that Fe-40Al coating presented a ferromagnetic character due to partial structure with a low degree of order and unmelted nanostructured particles retained from the feedstock. Moreover, the heterogeneous magnetic properties were found in the parallel and vertical direction of the coating.
