Abstract

PURPOSE:To obtain an Fe-Co alloy with superior wear resistance by adding one or more among Al, Cr, Mn and Mo to an Fe-Co alloy. CONSTITUTION:An Fe-Co alloy is manufactured by adding one or more among Al, Cr, Mn and Mo, e.g., 1% Al and 1.5% Cr to an Fe-Co alloy consisting of 49% Fe, 49% Co and 2% V. The manufactured alloy is formed into a magnet, and the magnet is nitrided. The resulting magnet has considerably improved wear resistance.

Conventionally, magnetizing and shaping magnets require high magnetic flux, and pure iron has been used to guide the magnetic flux.

As shown in Figure 1, pure iron has a saturation magnetization of approximately 20,000
Gaussian, %/J<2 As shown in Figure, it has been used for the yoke part of a magnetizing jig. However, in recent years, with the advent of rare earth-cobalt magnets, materials with higher saturation magnetization are needed, and Fe(49%)-Co(
49%) -V (2%) material with a saturation magnetization of 24,000 Gauss has begun to be used for magnetizing yokes and the like. However, this material has low hardness, and when used as a magnetizing yoke or mold, it is subject to severe wear. For example, the tip CA part of the magnetizing yoke wears out, and the gap with the magnet increases.
This caused a decrease in magnetization ability. This is the same with conventional pure iron), and when the magnetizing yoke wears out, the magnetizing jig itself must be remade, which has become a major factor in the increase in magnetizing costs.
