摘　　要：采用水气联合雾化工艺制备D_(50)分别为5.05(A1)、11.41(A2)、19.32(A3)、29.01μm(A4)的Fe_(76)Si_(9)B_(10)P_(5)合金粉末,研究粒度及粒度配比对Fe_(76)Si_(9)B_(10)P_(5)磁粉芯磁性能的影响。结果表明:随着粉末粒径的增大,磁粉芯的密度和μ_(e)增大,P_(s)、Ph与Pe升高;将4种不同粒度的Fe_(76)Si_(9)B_(10)P_(5)合金粉末进行四因素三水平的正交实验,当A1、A2、A3、A4质量分别为30、20、40、40 g时,磁粉芯获得最高μ_(e),在10 kHz下μ_(e)为25.8×10^(-3)H/m;当A1、A2、A3、A4质量分别为30、40、30、80 g时,磁粉芯获得最低P_(s),在100 mT,40 kHz下P_(s)为478 mW/cm^(-3)。Fe_(76)Si_(9)B_(10)P_(5)alloy powders with D50 of 5.05μm(A1),11.41μm(A2),19.32μm(A3)and 29.01μm(A4),respectively,were prepared by a water-gas atomization process,and the effects of the particle sizes and the particle size ratios on the magnetic properties of the Fe_(76)Si_(9)B_(10)P_(5)magnetic powder cores were investigated.The results show that the density andμe of the magnetic powder core gradually increase with the increase of the powder particle size,and Ps,Ph and Pe gradually increase.Four different particle sizes of Fe_(76)Si_(9)B_(10)P_(5)alloy powder were subjected to a four-factor,three-level Orthogonal method,and the magnetic powder core obtains the highestμe when the masses of A1,A2,A3,and A4 are 30 g,20 g,40 g and 40 g,respectively,theμe is 25.8×10^(-3)H/m at 10 kHz.When the mass of A1,A2,A3 and A4 are 30 g,40 g,30 g and 80 g,respectively,the magnetic powder core obtains the lowest Ps,and the Ps is 478 mW/cm^(-3)at 100 mT,40 kHz.
