Abstract
PURPOSE:To obtain a cathod-ray tube having a mesh electrode with thoroughly improved mechanical strength by a method wherein an Ni mesh surface is coated with aluminum and heated to form a nickel-aluminum alloy later. CONSTITUTION:A weight is placed on a mesh plane made of Ni to form an Ni mesh electrode with a desired shape. Subsequently, the evaporation method is emplyed to coat the surface of the Ni mesh electrode with Al uniformly. At this time, it is preferred to set the thickness of the aluminm coating at 2-6% of the thickness of the Ni mesh. Next the Ni mesh coated with Al is heated in a vacuum furnace or the one containing hydrogen at 800-1,000 deg.. In so doing, the Al on the surface of the mesh experiences heat expansion in Ni, so that Ni-Al alloy layer is formed on the surface of the Ni mesh. The mesh electrode completed shows extremely improved mechanical strength comparing with the conventional Ni mesh electrode or another coated with only Al.
