PADDING METHOD FOR MEMBER, REPAIR METHOD FOR MEMBER, BLADE PART OF GAS TURBINE, AND ELECTRODE FOR PILE

摘要

PROBLEM TO BE SOLVED: To facilitate the formation of a projection provided with a plane-like part in a leading edge in a leading edge of a member into an accurate shape by padding. SOLUTION: The electrical conductive member 100 provided with the projection 106 in which the plane-like part 110 is formed in the leading edge in the leading edge and a porous electrode 1 for pile provided with a plane-like part 7 corresponding to a shape of the plane-like part of the projection 106 of the member in the leading edge are provided by letting them separate from each other by small distance so that each plane-like part 7, 110 opposes mutually and becomes parallel. Pulse-like discharge is generated between the member 100 and the electrode 1 for pile. An electrode material of the electrode 1 for pile is piled in the leading edge of the projection 106 of the member 100 by discharge energy to form a padding part whose leading edge is like plane.
