Description
[軟磁性金属薄帯]
本発明に用いる軟磁性金属薄帯は、鉄系もしくはCo系の非晶質金属薄帯であることが好ましい。非晶質金属薄帯の厚さは一般的な10〜50μmの厚さのものを使用でき、目標とする原価や使用する磁気製品の周波数など用途によって最適な厚さが選ばれる。例えば、厚さを薄くすると渦電流損失が小さくなるため、高周波での損失をより小さくするためには20μm以下とすることが好ましい。他方、小型化のためには鉄心の占積率を高めたほうが好ましく厚くすることが好ましい。また、生産工数は、ほぼ積層数に比例するため、低価格のためには厚くすることが好ましい。
T(Fe、Coなど)の量aは、79%より少ないと鉄心材料として十分な飽和磁束密度BSが得られず磁心が大型化し好ましくない。十分な飽和磁束密度BSを得るために、さらに好ましくは、81%以上のT量が望ましい。また83%以上では熱安定性が低下し、安定した非晶質合金薄帯が製造できなくなるためである。回転機のロータやステータの用途では、コストとの関係から、Fe系の軟磁性合金薄帯とすることが好ましいが、求められる磁気特性から、Fe量の10%以下をCo、Niの少なくとも一種で置換することもできる。
Si量bは非晶質形成能に寄与する元素でBsを向上させるためには10%以下とする必要がある。さらにBsを向上させるためには、5%以下とすることが好ましい。
B量cは非晶質形成能に最も寄与し、10%未満では熱安定性が低下してしまい、18%より多いと添加しても非晶質形成能などの改善効果が見られない。
Cは材料の角形性およびBSを向上し磁心を小型化できると共に、低騒音化する効果がある。C量dは0.01%未満ではほとんど効果がなく3%より多くすると脆化と熱安定性が低下し、磁心製造が困難となり好ましくない。
Fe量の10%以下をNi、Coの一種または二種で置換すると飽和磁束密度BSが向上し、磁心の小型化に寄与するがコストが高い原料であるため10%より多く含有させるのは現実的ではない。
また、Mnは微量添加で若干BSを向上させる効果がある。0.50at%以上添加すると逆にBSが低下するため、好ましくは0.1%以上0.3%以下がよい。
また、Cr,Mo,Zr,Hf,Nbの1種以上の元素を0.01〜5%含んでもよく、不可避な不純物としてS,P,Sn,Cu,Al,Tiから少なくとも1種以上の元素を0.50%以下含有してもよい。
[ポリアミド酸溶液]
本発明において、軟磁性金属薄帯に塗布するポリアミド酸溶液は、熱硬化性のものが好ましく、一般的に市販されているポリアミド酸のNメチルピロリドン(NMP)溶液を、NMPで希釈して使用することが好ましい。例えば、市販のポリアミド酸溶液のポリアミド酸含有量は20重量%程度であり、NMP添加により、5〜15重量%に希釈して使用することができる。溶剤乾燥後の厚さを薄くすれば占積率が向上するが、ピンポールなどの欠陥発生率も増え、積層体で隣接する金属薄帯間の絶縁が不十分となる恐れがある。従って、乾燥後の厚さとしては、0.5ミクロン〜3ミクロンが好ましい。
[塗布乾燥]
その後、ポリアミド酸NMP溶液の塗布された軟磁性金属薄帯を半乾燥させる第一の熱処理(半乾燥熱処理)を行う。ポリアミド酸NMP溶液の乾燥は、乾燥温度が高すぎても、乾燥時間が長すぎても、イミド化が進行してしまう。好ましくは、最高温度200℃以下でかつ保持時間1分以下とする。乾燥炉内の風量を多くすることが好ましい。遠赤外線ヒーターによる乾燥方法も知られているが、遠赤外による乾燥は、ポリアミド酸分子に直接作用してイミド化を促進しやすいので、イミド化を高めすぎないよう配慮すべきである。この半乾燥熱処理により、ポリアミド酸溶液のイミド化率を15%以上70%以下とする。本発明におけるイミド化率は、樹脂のガラス転移点を超える温度で1時間熱処理を施したポリイミド酸溶液のイミド化率をFT−IR(赤外分析)により測定した値を100%として算出したものである。
[加工工程]
ポリアミド酸NMP溶液が塗布された軟磁性金属薄帯は、例えば、プレスにより所定形状が打ち抜かれる。その他にも、エッチングやレーザー加工などでより自由度の高い形状を、生産性高く得ることができる。また、最初に加工せず、後述する積層工程を行った後に、複数枚を一度に加工しても良い。
[積層工程]
所定形状に加工した軟磁性金属薄帯を、積層用の金型キャビティ内に入れ、複数枚を積層させる。積層体の上下には、圧をかけるための可動型が接するため、後工程の圧着工程後に積層体と稼動型が剥離できるよう、積層体と可動型との間に市販のカプトンやユーピレックスなどのポリイミドフィルム、またはテフロン(登録商標)フィルムなどを挟むと良い。
[加熱・圧着工程]
次に、積層された軟磁性金属薄帯に対して、加熱、圧着する第二の熱処理を行ない、積層体を形成する。積層された軟磁性金属薄帯は、金型ごと乾燥窒素雰囲気のホットプレス炉内に設置される。炉内を塗布したポリイミド膜のガラス転移点以上の温度に昇温する。この温度で保持した状態で、軟磁性金属薄帯同士を加圧して圧着する。保持する温度の上限は、樹脂の熱分解開始温度未満であれば問題ない。保持する時間は1分以上10時間以下が好ましい。この熱処理により、ポリアミド酸NMP溶液のイミド化率は30%以上にされる。
[焼鈍熱処理工程]
次に、第三の熱処理として、第二の熱処理時の温度より高い温度で軟磁性金属薄帯積層体を焼鈍する。非晶質金属薄帯は、焼鈍熱処理により、より良好な磁性特性を得ることができる。Fe系非晶質金属薄帯では300〜400℃、Co系非晶質金属薄帯では、300〜600℃で行われる。このとき、材料は脆化することが知られており、焼鈍熱処理中に非晶質合金薄帯積層体に加圧することは、非晶質合金薄帯積層体に欠けやクラックなどの欠陥を発生する恐れがある。よって、無負荷状態で焼鈍熱処理することが好ましい。機械的強度が必要な回転機コアなどの用途では通常この焼鈍熱処理は用いられない。また、焼鈍熱処理工程は、前工程の圧着工程の温度より高くなるため、イミド化率が高まる。この際、ポリアミド酸NMP溶液から水分が発生するので、金属薄帯表面の酸化防止のため、この焼鈍熱処理は圧着工程と同様の雰囲気とすることが好ましい。熱処理時間は0.1〜20hが好ましい。
Fe系非晶質金属薄帯として、平均厚さ25μm、幅50mm、長さ1000mのMetglas社製2605SA1材を用いた。このFe系非晶質金属薄帯を、内径3インチの紙巻に巻き取ってロール状にした(S100)。
以上の工程により、ポリアミド酸溶液が塗布・乾燥された非晶質金属薄帯を得た(S120)。
次に、打ち抜いた非晶質金属薄帯を、ステンレス製の積層金型内に30枚積み重ねた。積層した非晶質金属薄帯の上下端面と金型との間には、上記の同じ寸法形状で打ち抜いたポリイミドフィルムを挟み、非晶質金属薄帯と金型が固着することを防止した。
[比較例]
実施例1と同様にして、ポリアミド酸溶液を非晶質金属薄帯の両面へ塗布し、乾燥させ、その後その非晶質金属薄帯にプレス加工を施した。
その後、従来の製造方法と同様に、液体窒素雰囲気の乾燥炉内で保持温度300℃、熱処理時間30分のイミド化処理を行った。
