摘要
采用水气联合雾化法制备了Fe_(72)Si_(10.7)B_(10.7)Cr_(2.2)P_(1.5)C_(2.9)(at%)合金粉末,并利用扫描电镜、X射线衍射仪和DSC差示扫描量热仪、振动样品磁强计等分析检测手段研究了合金的晶体结构、非晶形成能力及磁性能。结果表明,水气联合雾化非晶粉末粒度较细,球形度较好且表面光洁,组织结构均匀,合金为单一的非晶结构;合金比饱和磁化强度达到167.61 A·m^2/kg,在100 kHz、Bm=100 mT条件下,合金磁粉芯铁损Pc<800 mW/cm^3,且在100 Oe条件下,其磁导率降幅仅为22%,综合软磁性能优异。
The Fe72Si10.7B10.7Cr2.2P1.5C2.9 alloy powders were produced by water-gas combined atomization. The phase structure, glass-forming ability and magnetic properties of the alloy powders were analyzed by SEM, XRD, DSC and VSM, respectively. The results pointed out that the powders made by water-gas combined atomization with fine particle size, is of spherical shape with smooth surface and uniform microstructure, and only single amorphous phase was observed; the specific saturation polarization of the alloy reaches the value of 167.61 A-m2/kg, the iron losses of the SMCs Pc 〈800 mW/cm3 at 100 kHz and Bm=100 roT, also the permeability decreases by only 22 % at 100 Oe. To sum up, the Fe-Si-B-Cr-P-C alloy exhibits excellent comprehensive soft magnetic performance.
