Abstract
An electrode is made of a metallic composite material including a matrix with embedded tubes having high burn-off resistance. A filler material, which differs from the material of the matrix and tubes, is used as a core material for the tubes. Such filler material promotes the emission of electrons from the electrode surface.
Claims16
An electrical discharge electrode for an electrical discharge gap, said electrode consisting of:
- a metallic composite material including tubes of a metallic material having a high burn-off resistance embedded in and contacting a metallic matrix material of high electrical conductivity and filled with a core material;
- and
- said core material consisting of a filler material which differs from said matrix and tube material and which promotes the emission of electrons from a surface of said electrode.
A method of producing an electrical discharge electrode consisting of a metallic composite material including tubes of a metallic material having a high burn-off resistance embedded in and contacting a metallic matrix material of high electrical conductivity and filled with a core material consisting of a filler material which differs from said matrix and tube material and which promotes the emission of electrons from a surface of said electrode, said method comprising:
- filling said tubes with said filler material;
- enclosing the thus filled tubes in a jacket of said matrix material;
- and
- jointly plastically shaping said jacket and enclosed, filled tubes, thereby forming said composite material.
