Description
また、その第2の目的は、加熱温度下での成形、いわゆる温間成形により、コア抵抗が高く低損失であるのみならず、高透磁率、高密度且つ高強度である新規な圧粉磁心を作製可能な軟磁性材料、及び、そのような圧粉磁心を簡易且つ低コストで製造し得る生産性及び経済性に優れる製造方法を提供することにある。
まず、鉄を主成分とする軟磁性粒子及び該軟磁性粒子の表面に形成された絶縁膜を有するコア粒子として、絶縁膜付き純鉄(ヘガネスAB社製、商品名:Somaloy 700、平均粒径200μm)を準備した。次に、トルエンに金属錯体としてジルコニウムテトラアセチルアセトナートを投入して、金属錯体含有塗布液を調製した。次に、絶縁膜付き純鉄に金属錯体含有塗布液を塗布した後、乾燥することにより、コーティング層を形成し、これにより、実施例1の軟磁性材料を作製した。なお、金属錯体の配合量は、絶縁膜付き純鉄に含まれる鉄に対するジルコニウムの割合で、0.057mol%とした。
その後、実施例1の軟磁性材料に潤滑剤としてステアリン酸亜鉛を0.1wt%添加し、その混合物を混合機(筒井理化学器械製、商品名:Vミキサー)に入れ、回転数12rpmで10分間混錬した。次いで、混錬した混合物(混錬物)を、成形温度130℃及び成形圧力980MPa(10ton/cm2)の条件で温間成形し、17.5mm×10.2mm、厚さ約4mmのトロイダルコア(成形体)を作製した。
このようにして得られた成形体を、5℃/minで550℃まで昇温し、その後さらに550℃で1時間保持することにより、実施例1の圧粉磁芯を作製した。なお、かかる熱処理時においては、150℃程度まで窒素雰囲気とし、その後、Air雰囲気に切り替えた。
ジルコニウムテトラアセチルアセトナートに代えてアルミニウムアセチルアセトナートを用いること以外は、実施例1と同様に処理して、実施例2の軟磁性材料及び実施例2の圧粉磁芯を作製した。なお、金属錯体の配合量は、絶縁膜付き純鉄に含まれる鉄に対するアルミニウムの割合で、0.285mol%とした。

熱処理時に600℃まで昇温し、その後さらに600℃で1時間保持すること以外は、実施例2と同様に処理して、実施例4の軟磁性材料及び実施例4の圧粉磁芯を作製した。
金属錯体含有塗布液の塗布を省略してコーティング層を形成しないこと以外は、実施例1と同様に処理して、比較例1の軟磁性材料及び比較例1の圧粉磁芯を作製した。
熱処理時に600℃まで昇温し、その後さらに600℃で1時間保持すること以外は、比較例1と同様に処理して、比較例2の軟磁性材料及び比較例2の圧粉磁芯を作製した。

実施例1〜4及び比較例1〜4の圧粉磁心につき、各種性能の測定を行った。表1に、評価結果を示す。
なお、磁気特性の評価は、BHアナライザー(IWASTU製、商品番号:SY−8258)を用いて、1T、1kHzでのコアロス(鉄損、(W/g))及び透磁率を測定した。強度は、抗折強度試験器(AIKOH ENGINEERING社製、商品番号:1311D)により、トロイダルコアの圧環強度を測定した。密度(g/cm3)は、トロイダルコアにおいて電子天秤により計測した重さとマイクロメータにより測定した体積から求めた。抵抗値(mΩ)及び電気抵抗率(mΩ・cm)は、トロイダルコアの両端の抵抗値を低抵抗計(TSURUGA製、Model 3569又は3568)で測定した後、下式に基づいて棒状試料の電気抵抗率に換算した。
電気抵抗率=(20.343×実測値)+418.92
金属錯体の配合量を表2に記載の通りに変更すること以外は、実施例1と同様に処理して、実施例5〜9の軟磁性材料及び実施例5〜9の圧粉磁芯を作製した。
