Abstract
Description
(1)少なくとも一方の面に点在する金属を有し、
点在する金属の大きさは直径1μm以上であり、
点在する金属がCuを含む、合金薄帯。
ビッカース硬度(Hv)=F/S=1.854×F/d2
本実施形態に係る合金薄帯において、合金薄帯本体の材料は、公知のものを用いることができ、例えば、アモルファス合金、微結晶合金、パーマロイ等の磁性合金などを用いることができる。アモルファス合金材料からなるものとしては例えば、Fe基アモルファス軟磁性材料、Co基アモルファス軟磁性材料からなるものなどがあり、また、微結晶合金材料からなるものとしては例えば、Fe基ナノ結晶軟磁性材料からなるものがある。具体例としては、Fe基アモルファス軟磁性材料としてはFe−Si−B−Nb−Cu系合金等が挙げられ、Co基アモルファス軟磁性材料としてはCo−Fe−Si−B系合金等が挙げられる。
X=100−(Ic/(Ic+Ia)×100)…(1)
Ic:結晶性散乱積分強度
Ia:非晶性散乱積分強度
本実施形態に係る合金薄帯は、その製造方法について特に制限されないが、例えば単ロール法により製造することができる。また、薄帯は連続薄帯であってもよい。
本実施形態に係る磁性部品、特に磁性コアおよびインダクタは本実施形態に係る合金薄帯から得られる。以下、本実施形態に係る磁性コアおよびインダクタを得る方法について説明するが、合金薄帯から磁性コアおよびインダクタを得る方法は下記の方法に限定されない。また、磁性コアの用途としては、インダクタの他にも、トランスおよびモータなどが挙げられる。
得られた合金薄帯に対し、剥離面の表面粗さ(算術平均粗さ)を測定した。剥離面の表面粗さは、JIS−B0601に準拠した接触式表面粗さ測定器を用いて測定した。接触式で3か所ずつ測定し、その平均値を表面粗さRaとした。
ビッカース硬度(Hv)は、マイクロビッカース硬さ試験で求めた。得られた合金薄帯に対面角136度のダイヤモンド正四角錐圧子を押込み、そのときにできる圧痕の寸法を測定し算出した。圧痕はCCDカメラで観察した。5回以上測定したときの平均値を、ビッカース硬度とした。
得られた合金薄帯から鋳造方向の長さが310mmである薄帯片を切り出した。次に、切り出した薄帯片を、外径18mm内径10mmのトロイダル状に120枚打ち抜き、打ち抜いた薄帯片を積層し、巻線を施して、高さ約3mm積層トロイダルコアを得た。なお、コア作製時に磁場中での熱処理は行っていない。
エネルギー分散型X線分光器(EDS)により、合金薄帯の剥離面に点在するCuを含む金属を検出した。その中から、直径が1μm以上である金属を抽出し、その頻度を算出した。また、検出した金属の組成を確認した。
合金薄帯の密着性を、引張せん断試験で評価した。JIS K6850に準拠し、試料厚みは、合金薄帯の厚みとした。得られた合金薄帯の試験片2枚を、500℃で、30秒、2t/cm2の圧力で積層した場合と、400℃で、30秒、2t/cm2の圧力で積層した場合とで密着性を評価した。密着性の評価の基準は、以下のとおりである。
A:3N/cm2(30kPa)以上
B:1N/cm2(10kPa)以上3N/cm2(30kPa)未満
C:1N/cm2(10kPa)未満
