Zusammenfassung:Heat treatments of alloys in fluidized bed reactors have been carried out for more than 25 years. Recently, this technology has been used for surface engineering applications in the deposition of hard and/or corrosion-resistant layers. In the present paper, we used fluidized bed technology (FBT) to deposit boride coatings. The coatings were examined by means of optical microscopy, Vickers microhardness and X-ray diffraction (XRD) in terms of coatings thickness and morphology, phase formation and properties. The as-produced coatings are characterized by very good adherence due to its tooth-shape morphology and it was found that only one phase belonging to Fe 2B (space group I 4/mcm, a=5.110 Å, c=4.249 Å) was formed during the treatment.
