摘要：
Iron-based alloys were sprayed on a copper substrate using high velocity oxy-fuel process to form amorphous coatings. Two modes of cooling were used, water and air, in order to increase the particles speed solidification. Structures and magnetic properties of FeNb and FeSi deposits have been characterized. X-ray diffraction patterns showed that FeNb coatings present a partially amorphous structure, however, in the case of FeSi alloys, their structure is completely crystalline. The use of the two modes of cooling has given almost the same results for the two types of powders. As a consequence, magnetic properties of this material could be improved by using a heat treatment.
