More Information
Summary:The present cathode for cathode ray tube of directly heating type is characterized by comprising a cathode substrate body having two leg pieces extended in the same direction and a flat part connected to one end of each leg piece, prepared by shaping a flat metal plate of nickel- or cobalt-based alloy, a bonding layer having an uneven surface prepared by diffusion bonding by heating a powder layer comprising powders of alloy or mixture of nickel and cobalt formed on the flat part, to which a thermionic emission layer is to be bonded, and the thermionic emission layer, and has a very small deformation when used and a longer life.
