In this paper, the FeSiBNbCu and FeSiBNbCu-Al coatings were synthesized
using cold spray technique in order to produce ferromagnetic materials.
Ultra-fine grain coatings are obtained using FINEMET nanostructured powders
mixed with Aluminum. Various percentages of Aluminum characterized by its
low hardness were taken in account. The obtaining coatings were formed of
Aluminum matrix and randomly distribution of FINEMET particles. Indeed,
magnetic measurements revealed a soft magnetic character for all the powders
and the coatings. 25% of Al was considered as ideal to produce a
homogenous coating with good soft magnetic properties.
