Abstract
Description
金属磁性材料および樹脂を含む圧粉磁心であって、
前記圧粉磁心の表面において微粒子が存在していることを特徴とする。
金属磁性材料として、重量比でSi/Fe=4.5/95.5であり、FeとSiとの
合計量が99重量%であるFe−Si系合金粒子をガスアトマイズ法で作製した。なお、当該Fe−Si系合金粒子の粒子径の中央値(D50)は30μmであった。
囲気下、600℃で0.5時間〜3時間行った。なお、最終的に得られる圧粉磁心表面における微粒子の平均粒径および粒径の標準偏差σを表1および表2に記載した大きさにするため、第1焼成の条件を制御した。
で24時間塩水噴霧試験を行った。塩水噴霧後、3mm×3mmの測定部位をランダムに10か所設定した。各測定部位について、光学顕微鏡(倍率50倍)に備え付けたカメラにより撮影し、各測定部位の錆面積比率を算出した。そして、10か所の測定部位の平均の錆面積比率を算出した。平均の錆面積比率が15.0%以下である場合を良好とした。そして、10.0%以下である場合をより良好とし、5.0%以下である場合を最も良好とした。
