Production of high-performance three-layer emitters of X-ray tube cathodes by diffusion welding

The paper presents the description of the investigation of x-ray tube cathode emitters made of refractory metals by diffusion welding. The weld seam structure has been analyzed. Comparison of the emissivity characteristics of three-layer Ta-W-Ta and Nb-W-Nb cathode emitters has been made.
