Indirect cathode sleeve manufacturing method |
摘要 |
An indirect cathode sleeve and manufacturing method thereof capable of substantially reducing electric power consumption of a heater disposed inside the cathode sleeve and simultaneously reducing a picture-producing time by oxidizing an inside surface of the cathode sleeve and reducing an outside surface thereof. The cathode sleeve includes a heater disposed inside the cathode sleeve; a base metal formed at the top of the cathode sleeve; an electron-emitting material layer formed at the outside surface of the base metal; and an indirect cathode sleeve including a black inside surface and a white outside surface. The method for manufacturing the indirect cathode sleeve includes the steps of forming a structure of a cathode sleeve consisting of a bimetal which consist of a Nickel-Chrome alloy at an inside surface of the cathode sleeve and a Nickel alloy at an outside surface of the cathode sleeve; oxidizing the inside surface of the cathode sleeve through a high temperature wet hydrogen environment; selectively etching the outside surface of the cathode sleeve and, as a result, forming a base metal at the top of the cathode sleeve; and forming an electron-emitting material layer at the outside surface of the base metal.
