摘　　要：介绍了YF-65伺服阀用马蹄形AlNiCo磁钢以及磁场热处理、回火等工艺对磁性能的影响。最佳磁场热处理和回火后试样性能为：Br=1350mT；Hc=62．1kA／m;BHmax=54．1kJ／m3；器件间隙磁通密度达到225mT～235mT。The in fluences of magnetic field heat treatment and multiple tempering on the magnetic properties of an AlNthe magneticsteel horseshoe intended for a YF-65 servo valve are studied in this paper. After optimum magnetic field heat treatment and multipletempering, Br, Hc, (BH)max and the appliance gap magnetic flux density are 1350 mT, 62.1 kA/m, 54. 1 kJ/m3 and 225 mT^235mT, respectively.
