Abstract

To provide a cladding material excelling in deep-draw moldability for cup-shaped discharge electrode; a process for producing the same; etc. There is provided a cladding material comprising foundation layer (1) of pure Ni or Ni foundationed alloy composed mainly of Ni and surface layer (2) of pure Nb whose oxygen content is 550 ppm or below. This surface layer (2) is diffusion bonded directly or through an NiNb intermetallic compound layer of 8.0 m or less to the foundation layer (1). Preferably, the surface layer (2) is diffusion bonded to the foundation layer (1) by continuous annealing in an atmosphere of Ar gas whose dew point is -40 DEG C or below. This continuous annealing realizes efficient diffusion bonding of the surface layer (2) to the foundation layer (1) while easily suppressing the oxygen content of the surface layer (2) to 550 ppm or below.
