Apparatus for separating metal coating film and method for separating metal coating film

摘要

A metal coating removing apparatus ( 1 ) includes a first electrode ( 13 ) arranged so as to be opposed to a metal coating ( 101 ) as an object to be removed, a second electrode 14 arranged so as to be opposed to the metal coating ( 101 ) at a predetermined distance from the first electrode ( 13 ), and a pulse power generator ( 11 ), for example, that functions as a discharge energy supply portion. The pulse power generator ( 11 ) supplies discharge energy between the first electrode ( 13 ) and the second electrode ( 14 ) so as to allow discharging to occur between the first electrode ( 13 ) and the second electrode ( 14 ). By allowing discharging to occur between the first electrode ( 13 ) and the second electrode ( 14 ), the metal coating ( 101 ) can be removed.
