Method for Producing Soft Magnetic Metal Powder Coated With Mg-Containing Oxide Film and Method for Producing Composite Soft Magnetic Material Using Said Powder |
摘要 |
A method for producing a soft magnetic metal powder coated with a Mg-containing oxide film, comprising the steps of adding and mixing a Mg powder with a soft magnetic metal powder which has been subjected to heating treatment in an oxidizing atmosphere at a temperature of 40 to 500° C. to obtain a mixed powder, and heating the mixed powder at a temperature of 150 to 1,100° C. in an inert gas or vacuum atmosphere under a pressure of 1x10<SUP>-12 </SUP>to 1x10<SUP>-1 </SUP>MPa, while optionally tumbling; and a method for producing a composite soft magnetic material from the soft magnetic metal powder coated with a Mg-containing oxide film.
