Abstract
The utility model provides a novel ceramic tube shell provided with a tube shell. A metallizing layer is coated on the surface of the end parts of the tube shell, is manufactured by virtue of advanced ceramic isostatic pressing process and high-temperature metalization process, and has the characteristics of high electric insulating strength and mechanical strength and good seal airtightness, thereby being extensively applied to X-ray tubes.
Description
Technical field
The utility model belongs to vacuum electronic unit, devices field, is specifically related to a kind of new ceramics shell.
Background technology
The X-ray tube is widely used in being used for the Non-Destructive Testing of medical diagnosis, treatment, part, aspects such as structure of matter analysis, spectrum analysis, scientific research in various X-radiometers and the detector.The shell of X-ray tube has pottery and two kinds in glass, and ceramic cartridge has more superiority than glass shell at aspects such as mechanical strength, dielectric strength, air-tightness, and ceramic cartridge is widely used at present as one of core component of X-ray tube.Ceramic cartridge is used for the X-ray tube not only will have reliable electrical insulation capability, also high mechanical strength will be arranged, and simultaneously reliable sealing-in air-tightness will be arranged also with the metal parts sealing-in time, and existing shell can't satisfy above-mentioned requirements.
The utility model content
The technical problem that the utility model solves: a kind of new ceramics shell is provided, it is manufactured and adopts advanced ceramic isostatic pressing process and high temperature metallization explained hereafter, have characteristics such as electric simulation strength height, mechanical strength height, sealing-in air-tightness be good, be widely used in the X-ray tube.
The technical solution adopted in the utility model: a kind of new ceramics shell, have shell, described shell end surface has metal layer.
Described metal layer is two circles, and the outer ring is metal layer I, and inner ring is metal layer II, and the metal layer of described outer ring and inner ring is arranged in concentric circles.
The utility model compared with prior art, the high-temperature metal metallization processes is adopted in ceramic metallization, at ceramic surface coating layer of metal powder, behind high temperature sintering, form a kind of firm, fine and close metal layer, thereby realize the welding of pottery and metal, have characteristics such as sealing strength height, air-tightness are good, reliability height.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is a structure vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.
A kind of new ceramics shell has shell 1, and shell 1 end surface has metal layer 2; Metal layer 2 is two circles, and the outer ring is metal layer I 3, and inner ring is metal layer II 4, and the metal layer of outer ring and inner ring is arranged in concentric circles.
Production technology: ceramic cartridge 1 is made and is adopted isostatic pressing process, with ceramic raw material after system material, granulation, pack in the special-purpose mould, in isostatic pressing machine, be pressed into ceramic blank, be processed into needed shape through car system, by hard-fired ware, after mill processing reaches required overall dimensions precision.The high-temperature metal metallization processes is adopted in ceramic metallization of the present utility model, at ceramic cartridge 1 end surface coating layer of metal powder, behind high temperature sintering, form a kind of firm, fine and close metal layer 2, thereby realize the welding of pottery and metal, this product has characteristics such as sealing strength height, air-tightness are good, reliability height.
