Description
この実施の形態に係る圧入接合において、基本的な圧入接合に係る工程及び作用は上記従来技術の欄で説明したのと同様であり、ここでの詳しい説明は省略する。
23,27 孔部
24,28 第二部材
Claims (1)
- 孔部を有する第一部材と、
この第一の部材との間に所定の圧入代を有し、上記第一部材と同一材質の材料からなる第二部材とを用い、
上記第一部材の孔部を円形に形成する一方、上記第二部材を円形の軸体に形成し、
上記材料としてフェライト組織を有する炭素鋼、オーステナイト組織を有する合金鋼、或いはフェライト組織を有する合金鋼を用い、
上記第一部材の孔部内に上記第二部材を所定の圧力で押圧するとともに、これら両部材間に通電して両者の接合部に電気抵抗熱を発生させ、上記第二部材を上記孔部に圧入し、上記第二部材と上記孔部との両壁面同士の滑り方向の移動によってしごくことにより表面の層が削られ清浄化された接合界面を形成させ、かつこの接合を固相状態の接合とした圧入接合を行い、
上記圧入接合により接合部に塑性変形が生じかつ焼きが入った接合部材を、通常の加熱炉または連続炉によりA1変態点以上、又は再結晶以上の温度で且つ拡散焼き鈍しの温度1150℃より低い温度で、1時間以上3時間以内の時間加熱保持して焼き鈍しを行い、この熱処理により接合部を分散・消滅させ、上記圧入接合により接合した両部材の接合部における金属組織を一体化又は均質化させることを特徴とする圧入接合における熱処理方法。
