Title:
SOFT MAGNETIC ALLOY POWDER HAVING SHAPE ANISOTROPY AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH04147903
Kind Code:
A
Abstract:
PURPOSE: To produce soft magnetic alloy powder having shape anisotropy and superior mechanical strength by forming Cr oxide coating films on the surfaces of the particles of magnetic powder of an alloy based on Fe-Si contg. a specified amt. of Cr and specifying the oxygen content of the particles.
CONSTITUTION: Cr oxide coating films are formed on the surfaces of the particles of magnetic powder of an alloy contg. Fe, Si and Cr as essential components and having 2-10wt.% Cr content in Fe-Si and the oxygen content of the particles is regulated to 100-10,000ppm. Soft magnetic alloy powder having shape anisotropy and enhanced strength is obtd.
