RARE-EARTH-ELEMENT-FE-CO-B PERMANENT MAGNET POWDER EXCELLENT IN MAGNETIC ANISOTROPY AND CORROSION RESISTIVITY AND BONDED MAGNET THEREFROM

摘要

By containing one or two or more of Ti, V, Nb, Ta, Al, and si, R-Fe-Co-B-based permanent magnet powder having excellent magnetic anisotropy and corrosion resistance can be obtained by H ₂ treatment alone. The manufacturing cost can be greatly reduced without the need for daily firing for flattening.
