Description

Fremgangsmåte til innbyrdes forbindelse av deler av keramisk materiale ved hjelp av et godt ledende metall. Method for interconnecting parts of ceramic material using a well-conducting metal.

Oppfinnelsen angår en fremgangsmåte The invention relates to a method

til innbyrdes forbindelse av deler av keramisk materiale ved hjelp av et godt ledende metall, særlig uten at delene er metallisert på forhånd. for the mutual connection of parts of ceramic material by means of a well-conducting metal, in particular without the parts being metallized in advance.

For å forbinde deler av keramisk materiale med hverandre, ble de ofte først To connect parts of ceramic material with each other, they were often first

metallisert, f. eks. ved pådampning av et metallized, e.g. by vaporizing a

metall eller ved påsmøring av en sølv-pasta, hvoretter de metalliserte overfla-ter ble loddet sammen. En direkte forbindelse av ikke metalliske gjenstander kan metal or by applying a silver paste, after which the metallized surfaces were soldered together. A direct connection of non-metallic objects can

skje ved anvendelse av titanholdige lege-ringer av f. eks. gull, sølv, kobber eller aluminium. happen by using titanium-containing alloys of e.g. gold, silver, copper or aluminium.

Det har vist seg at ikke metalliserte It has been shown that not metallized

deler av keramisk materiale uten videre parts of ceramic material without further ado

kan forbindes med hverandre ved hjelp av can be connected to each other by means of

et godt ledende metall, f. eks., gull, sølv, a well-conducting metal, e.g., gold, silver,

kobber, aluminium eller en legering av copper, aluminum or an alloy thereof

disse, når delene ifølge oppfinnelsen legges these, when the parts according to the invention are placed

på hverandre med et mellomlegg av en folie av disse metaller og deretter opphetes on each other with an interlayer of a foil of these metals and then heated

over smeltepunktet i så lang tid at der above the melting point for such a long time that there

etter avkjøling er tilveiebragt fast forbindelse mellom delene. after cooling, a firm connection is provided between the parts.

Dette kan sannsynligvis føres tilbake This can probably be reversed

på den kjennsgjerning at metallet som on the fact that the metal which

følge av kapillarvirkning holdes fast mellom delene og forbinder disse med hverandre. as a result of capillary action is held firmly between the parts and connects them to each other.

Når den på denne måte dannede gjen-stand igjen opphetes, og når delene skilles When the object formed in this way is heated again, and when the parts are separated

fra hverandre, konsentrerer metallet seg apart, the metal concentrates

som små kuler på overflaten. Det er derfor like small balls on the surface. That is why

overraskende at det allikevel kan dannes surprising that it can still form

en stiv, vakuumtett forbindelse. a rigid, vacuum-tight connection.

Oppfinnelsen skal forklares nærmere under henvisning til tegningen som viser et elektrisk utladningsrør, hvis vegg består av deler av keramisk materiale, f. eks. aluminiumoksyd. The invention will be explained in more detail with reference to the drawing which shows an electric discharge tube, the wall of which consists of parts of ceramic material, e.g. aluminum oxide.

På figuren betegner 1 bunnplaten, f. eks. av aluminiumoksyd (A1203), i hvil-ken der er festet stifter 2. På stiftene er anordnet et elektrodesystem 3 som er sent-rert i en sylindrisk ring 4 av aluminiumoksyd. Røret er i den øvre ende lukket med en plate 5, som også består av aluminiumoksyd. In the figure, 1 denotes the base plate, e.g. of aluminum oxide (A1203), in which pins 2 are attached. An electrode system 3 is arranged on the pins, which is centered in a cylindrical ring 4 of aluminum oxide. The tube is closed at the upper end with a plate 5, which also consists of aluminum oxide.

Delene 1, 3 og 5 stables på hverandre i en vakuumklokke, med mellomlegg av folier 6 av gull, kobber, aluminium eller sølv, og opphetes over metallets smelte-punkt. Jo høyere opphetningstemperatu-ren overskrider smeltepunktet, jo kortere kan opphetningstiden være. Det har vist seg at ved anvendelse f. eks. av gull, er det tilstrekkelig med en opphetning til 1300° C i 15 minutter. Derved smelter metallet og danner en fast forbindelse mellom alundrumdelene. The parts 1, 3 and 5 are stacked on top of each other in a vacuum bell, with interlayers of foils 6 of gold, copper, aluminum or silver, and heated above the metal's melting point. The higher the heating temperature exceeds the melting point, the shorter the heating time can be. It has been shown that when applying e.g. of gold, heating to 1300° C for 15 minutes is sufficient. Thereby the metal melts and forms a firm connection between the aluminum drum parts.
