Structural study of iron-based microstructured and nanostructured powders sprayed by HVOF thermal spraying

For FeSi coatings sprayed using nanocrystalline powders, X-ray diffraction showed the crystalline size was lower than that in the coating obtained from microcrystalline powder. For FeSiB alloys, the structure is crystalline with a small quantity of amorphous phase. FeSi coatings behaved as a soft ferromagnetic. On other hand, the FeSiB coatings presented.
