Description
以下、図面を参照して本発明の一実施形態を説明する。図1はアルミニウムなどの金属板1に表面改質処理を施している状態を示す。金属板1の表裏面には金属酸化被膜2が形成されている。金属板1の一方の面にパルスレーザ3を照射しながら走査することにより、金属酸化被膜2を溶融し凝固させ、金属酸化被膜2を表面改質して表面改質薄膜4とする。このとき、表面改質は、後にかしめを施す部分の全面に隙間なく行う。表面改質薄膜4は粗大な結晶からなる脆い組織である。
次に、図2に示すように、2枚の金属板1を表面改質薄膜4が向かい合うように重ね合わせて積層金属板5を形成し、積層金属板5に断面円形の凹部6aを有するダイス6と断面円形のポンチ7によって加圧成形する。ポンチ7は図示しない駆動機構によりダイス6に対して接近離間可能とされ、ポンチ7の先端部の径は、ダイス6の凹部6aの径よりも小径とされている。
以下、実施例を参照して本発明をさらに詳細に説明する。
図3は厚さ1mmのアルミニウム(株式会社神戸製鋼所製アルミニウム合金:6K21)の圧延材の表面を示す写真であり、同図(A)は倍率を100倍、(B)は倍率を500倍にして撮影したものである。これらの図に示すように、圧延材の表面には微細な圧延ローラの痕が残っている。
上記圧延材および表面改質した金属板にJISZ2248に準拠してV字曲げ試験を行った。V字曲げ試験は、V字状に所定角度で屈曲した押圧面を有する雄型および雌型に試料を挟んで屈曲させる試験である。金属板のV字曲げ試験では、表面改質した部分がV字の角側となるようにした。
実施例1で用いた圧延材の片面の金属酸化被膜をワイヤブラシを用いて除去し、その面が向かい合うように2枚の圧延材を重ね合わせて積層金属板を形成した。また、実施例1で表面改質を行った面が向かい合うように2枚の金属板を重ね合わせて積層金属板を形成した。この場合において、圧延材と金属板は短冊状とし、それらを長手方向に互いにずらして積層金属板とした。これらの積層金属板に対して図7に示すかしめ装置(TOX社製)を用いて図7に示すような形状に成形し、かしめ接合を行った。かしめ装置は、凹部6aを有するダイス6とポンチ7とを備え、ポンチ7をダイス6に接近離間させる構造のものである。凹部6aの底部の周縁には、一段低くなった窪みが形成され、成形された積層金属板の材料が窪みに入り込んで材料の境界部で互いに噛み合うようにかしめ成形される。

- 前記表面改質薄膜は、前記金属板どうしの向かい合った面の双方に施されることを特徴とする請求項1に記載の金属接合体。
- 金属板の表面の少なくともかしめを施す表面部に、高エネルギービームを照射して該表面の金属酸化被膜を溶融および凝固して表面改質薄膜を形成し、前記表面改質薄膜どうしが向かい合うように複数の前記金属板を重ね合わせて積層金属板を形成し、
前記積層金属板を工具により加圧成形してかしめを施すことを特徴とする金属接合体の製造方法。 - 前記高エネルギービームがパルスレーザであることを特徴とする請求項3に記載の金属接合体の製造方法。
