【発明の詳細な説明】 本発明は固相接合法に係り、特に被接合部材を電磁力に

従来のろう接、拡散接合、ＴＬＰ接合等の面相接合にお

及び空圧プレスでめったすした。しかし装置は複雑で大

イド状欠陥や接合不良など発生しやすく、また接合部に
偏析が多く、かつ変形しやすい等のような欠点があった

本発明の目的は、従来孜術の欠点をなくシ、被接合部材

本発明は、被接合部材の周囲に励磁コイル設け、磁界を
発生させることによって発生する電磁力で加圧、振動し
ながら所定の接合温度に加熱、保持して接合する方法で
ある。
本発明の接合方法において、例えば第１図に示すように
、励磁コイル１に直流電流を流すと磁界が発生して加圧

可能である。
上記した接合方法において、電磁力によるガロ圧後、励
磁コイル１にパルス電流を流すことによってパルス磁界
が発生し、加圧ヘッド２は振動加圧を行ない、接合部材
３，４に振動圧力が加わる。
この振動圧力により、接合部材の接合面のなじみが良く
なってボイド状欠陥や接合不良などの欠陥を防止できる
。さらに接合後、上記した振動圧力を〃口えることによ
り、接合層の拡散が進行し、接合面に生じゃすい偏析等
を少なくすることができる。
上記のよりな〃ａ圧方式において、第２図に示すように
被接合部材の両方の周囲に励磁コイルを設け、被接合部
材を両側から圧力を加える方法や第３図に示すよ−うに
被接合部材の一方に励磁コイルを複数個設け、励磁コイ

要は加圧方法は適宜選定できる。
本発明の接合法として、従来から用いられている〃０圧
方法で振動加圧を行なっても同様の効果が期待できる。
以下、実施例によって本発明の詳細な説明する。
第１図に示す本発明の装置で被接合部材３，４としてＮ

第１表 本発明の加圧方法を第４図に示す。またインサート材と
してＪＩ８ＢＮｉ−２を使用した。
上記のようにして得られた本発明の接合方法による接合
部は、接合不良やボイド欠陥もなく、ろう材の拡散が進
行し偏析も少なく、良好であった。
また比較のため行なった通常の接合で行なった接合部で
は、接合欠陥がなく接合されているが、ろう材が拡散で
きずに多少存在して偏析している状態である。以上のよ
うに本発明の振動加圧を行なう接合法によって、接合後
のろう材の拡散が従来の接合法に比べ進行し、均一な接
合部を得ることができる。また従来の接合法に比べ接合
温度は低く、接合時間も少なくできる。
本発明によれば、一般に用いられている油圧式プレス装
置のように複雑で大型化にもならず簡便で、励磁電流の
調整で微小な圧力を容易にコントロールでき、接合部材
に均一な圧力を加えることができるので性能の向上及び
経済性の効果がめる。
さらに励磁コイルにパルス電流を流し、振動加圧を行な
うことによってボイド状欠陥や接合不良を防止上、接合
後の偏析を少なくシ、なおかつ接合面の歪効果により接
合温度を低くできるので接合部の品質が著しく向上する
