Abstract:
The oblong bulb (1) of the lamp is sealed at opposing ends by sealing pieces (6; 32), with application of a holder to each end, whereby said holder comprises an electrical contact element (13; 25), electrically connected to a power supply (15; 21), running to the lighting means. The contact element is housed in a tubular extension (11; 22) of the sealing piece and the maximum external diameter of the contact element (13; 25) is loosely matched to the inner diameter of the sleeve.
Abstract:
A high-temperature-resistant composite body is formed by joining over an area of a first, nonmetallic section via a bonding solder layer to a second, metallic section composed of Mo, an Mo-based alloy, W or a W-based alloy. A first arrangement composed of the first section, a first Zr solder and an intermediate layer is firstly soldered together in a first soldering step. A second arrangement of the resulting partial composite body, a second solder adjoining the intermediate layer and the second section is subsequently soldered together in a second soldering step. The intermediate layer at least 90 atom % of at least one of the elements Ta, Nb, W. The second solder is formed by precisely one material selected from Ti, Ti-based solder combination, V-based solder combination, Zr or Zr-based solder combination and it melts at a lower temperature than the first Zr solder in the second arrangement.

Abstract:
The present invention relates to a process for producing a high-temperature-resistant composite body (2) by joining an area of a first, nonmetallic section (10) via a bonding solder layer (12) to a second, metallic section (6) composed of Mo, an Mo-based alloy, W or a W-based alloy. Here, a first arrangement composed of the first section (10), a first Zr solder and an intermediate layer is firstly soldered together in a first soldering step. A second arrangement composed of the resulting part composite body, a second solder adjoining the intermediate layer and the second section (6) is subsequently soldered together in a second soldering step. The intermediate layer is formed here to an extent of at least 90 atom% from at least one of the elements Ta, Nb and/or W. The second solder is formed by precisely one material from the group consisting of Ti, Ti-based solder combination, V-based solder combination, Zr or Zr-based solder combination and is selected such that it melts at a lower temperature than the first Zr solder in the second arrangement.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines hochtemperaturfesten Verbundkörpers (2) durch flächiges Verbinden eines ersten, nichtmetallischen Abschnittes (10) über eine Lötverbundschicht (12) mit einem zweiten, metallischen Abschnitt (6) aus Mo, einer Mo-basierten Legierung, W oder einer W-basierten Legierung. Dabei wird zunächst eine erste Anordnung aus dem ersten Abschnitt (10), einem ersten Zr-Lot und einer Zwischenschicht in einem ersten Lötschritt verlötet. Anschließend wird eine zweite Anordnung aus dem erhaltenen Teil-Verbundkörper, einem an die Zwischenschicht angrenzenden, zweiten Lot und dem zweiten Abschnitt (6) in einem zweiten Lötschritt verlötet. Die Zwischenschicht ist dabei zu mindestens 90 at.% aus mindestens einem der Elemente Ta, Nb und/oder W gebildet. Das zweite Lot wird durch genau ein Material der Gruppe Ti, Ti-basierte Lotkombination, V-basierte Lotkombination, Zr oder Zr-basierte Lotkombination gebildet und ist derart gewählt, dass dieses in der zweiten Anordnung bei einer niedrigeren Temperatur als das erste Zr-Lot schmilzt.
