Title:
CLADDING MATERIAL FOR DISCHARGE ELECTRODE AND DISCHARGE ELECTRODE
Document Type and Number:
WIPO Patent Application WO2005048285
Kind Code:
A8
Abstract:
Disclosed is a discharge electrode material which enables to form a discharge electrode having a life and discharge characteristics equivalent to those of a discharge electrode which is mainly composed of Nb. Furthermore, the discharge electrode material is excellent in weldability to a supporting conductor and enables to reduce the material cost. The cladding material for discharge electrodes comprises a base layer (1) composed of pure Ni, an Ni-base alloy mainly containing Ni or a stainless steel, and a surface layer (2) whichi is joined to the base layer (1) and composed of pure Nb or an Nb-base alloy mainly containing Nb. An intermediate layer composed of a stainless steel is preferably arranged between the base layer (1) and the surface layer (2). The base layer (1) may be formed as a band plate and the surface layer (2) may be superposed only on the central portion of the base layer (1).
