摘要：
The paper deals with the structure and magnetic properties of coatings obtained by HVOF spraying using microcrystalline and nanocrystalline powders. For FeNb coatings sprayed using microcrystalline powders, X-ray diffraction showed partially amorphous structure. For FeSi ones, the structure was completely crystalline. 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.
