本文概述了记录磁头工作缝隙磁场强度、重放磁头分路系数与材料导磁率的关系。介绍了三种新研制的耐磨磁头合金(Fe-Ni-Nb合金、Fe-Ni-Nb-Al合金,Fe-Ni-Nb-Mo-Al合金)的化学成分、电阻率、维氏硬度、居里温度,并列表示出合金的静态参数和动态参数。
This paper summarizes the relationship between the magnetic field intensity of the working gap of the recording head, the shunt coefficient of the reproducing head and the permeability of the material. The chemical compositions, electrical resistivity, Vickers hardness, wear resistance and wear resistance of three newly developed wear-resistant magnetic head alloys (Fe-Ni-Nb alloy, Fe-Ni-Nb-Al alloy and Fe-Ni-Nb-Mo-Al alloy) Curie temperature, and lists the static and dynamic parameters of the alloy.
