METHOD FOR PRODUCING MODIFIED GREEN COMPACT, AND POWDER MAGNETIC CORE OBTAINED BY THE PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a green compact for a powder magnetic core whose mechanical strength is more excellent. SOLUTION: The method for producing a modified green compact is characterized in that a green compact obtained by compressing an iron-based soft magnetic powder having a phosphoric acid chemical conversion coating film is brought into contact with water in a supercritical state.
