Title:
PROCESS FOR PRODUCING ELECTRODE FOR DISCHARGE SURFACE TREATMENT AND METHOD OF DISCHARGE SURFACE TREATMENT
Document Type and Number:
WIPO Patent Application WO/2008/010263
Kind Code:
A1
Abstract:
A process for producing an electrode for discharge surface treatment that is
employed in a discharge surface treatment in which providing an electrode of
molded powder obtained by molding of a metal powder or metal compound powder or
ceramic powder, pulsed discharge is induced between the electrode and a work
in a processing liquid or gas so that by the discharge energy, the work surface
is provided with a coating of electrode material or a coating of substance resulting
from reaction of the electrode material by the pulsed discharge energy. The process
comprises feeding under pressure a mixture having plasticity obtained by mixing
a metal powder or metal compound powder or ceramic powder with a binder into a die
corresponding to electrode contour to thereby obtain a molded form and heating
the molded form so as to remove binder components, thereby achieving production
of an intended electrode.
