Abstract
【解決手段】一方の部材を他方の部材に当接させて被接合界面を形成する第一工程と、被接合界面に対して略垂直に圧力を印加した状態で、一方の部材と他方の部材とを同一軌跡上で繰り返し摺動させ、被接合界面からバリを排出させる第二工程と、摺動を停止して接合面を形成する第三工程と、を有し、圧力を、所望する接合温度における一方の部材及び/又は他方の部材の降伏応力以上かつ引張強度以下に設定すること、を特徴とする線形摩擦接合方法。
【選択図】なし
Description
一方の部材を他方の部材に当接させて被接合界面を形成する第一工程と、
前記被接合界面に対して略垂直に圧力を印加した状態で、前記一方の部材と前記他方の部材とを同一軌跡上で繰り返し摺動させ、前記被接合界面からバリを排出させる第二工程と、
前記摺動を停止して接合面を形成する第三工程と、を有し、
前記圧力を、所望する接合温度における前記一方の部材及び/又は前記他方の部材の降伏応力以上かつ引張強度以下に設定すること、
を特徴とする線形摩擦接合方法を提供する。
第一工程は、一方の部材2を他方の部材4に当接させて被接合界面6を形成する工程である。接合部の形成を所望する箇所に一方の部材2及び/又は他方の部材4を移動させ、被接合面同士を当接させ、被接合界面6を形成する。
第二工程は、被接合界面6に対して略垂直に圧力Pを印加した状態で、一方の部材2と他方の部材4とを同一軌跡上で繰り返し摺動させ、摺動の方向と略平行及び略垂直に被接合界面6からバリ8を排出させる工程である。
第三工程は、第二工程における摺動を停止して接合面を形成する工程である。本発明の線形摩擦接合方法においては、被接合界面6の全面からバリ8が排出された後に摺動を停止させることで、良好な接合体を得ることができる。なお、第二工程において被接合材に印加した圧力Pはそのまま維持してもよく、バリ8を排出すると共に新生面をより強く当接させる目的で、より高い値としてもよい。
4・・・他方の部材、
6・・・被接合界面、
8・・・バリ。
