PROBLEM TO BE SOLVED: To provide an electro-polishing method which is suitable for preparing an analysis sample of a metallic material. SOLUTION: This method for electrolytically polishing the surface of an object P to be polished comprises the steps of: providing a pair of electrodes 14 and 15 in an electrolytic tank 13; charging an electrolytic solution into the electrolytic tank; stirring the electrolytic solution by rotating a rotator 25; employing a basket-shaped electrode 15 in one side of the pair of the electrodes; charging the object to be polished into the basket-shaped electrode; and electrolytically polishing the object by passing an electric current between the pair of the electrodes while moving the basket-shaped electrode up and down in the electrolytic solution. It is recommended to cool the periphery of the electrolytic tank with cooling water. It is also recommended to change a direction of passing the electric current between the pair of the electrodes at a predetermined time interval. COPYRIGHT: (C)2008,JPO&INPIT |
