| description | To provide a method and a tool for measuring residual stress distribution in depth direction capable of performing accurately electrolytic polishing even for a complicated shape.SOLUTION: Electrodes are embedded to a tool provided with a groove which has an opening and secures a channel parallel to an object between the object and the opening when the opening is pushed against the object, the opening and the electrodes are directed to the object, the tool is pushed against the object, an electrolytic solution is caused to flow in parallel to the object through the channel, at the same time, an electric current is applied between the electrodes and the object for a given time, after the constant time elapses, the electrolytic solution is recovered, the tool is removed and a residual stress is measured on a polished surface.SELECTED DRAWING: Figure 6
【課題】複雑形状であっても正確に電解研磨をする。【解決手段】開口を備えた溝であって、前記開口を前記対象物に向けて押し当てると対象物に平行な流路が前記対象物との間に確保される溝を備えた治具に、前記溝内において前記対象物に平行になるように電極を埋め込み、前記開口および前記電極を前記対象物に向けて前記治具を前記対象物に押し当て、前記流路に電解液を前記対象物に平行に流しながら、一定の時間、前記電極と前記対象物との間に電流を印加し、前記一定の時間が経過した後、前記電解液を回収して前記治具を取り外し、研磨された面において前記残留応力を測定する。【選択図】図６ |
