Definitions
- the invention relates to a sealing film and associated lamp with this film according to the preamble of claim 1. It is in particular molybdenum foils, which find application in bruises, as they are customary for the sealing of incandescent lamps and discharge lamps.
- the film is provided with a protective layer of Al, Cr, Si, Ti or Ta.
- the thickness is 5 to 100 nm.
- a similar technique is known from DE-A 30 06 846, in which for the same purpose layers of Ta, Nb, V, Cr, Ti, Y, La, Hf or Sc are used.
- the layer thickness is 10 to 200 nm.
- a partial chrome plating is usually used for the protection of the molybdenum foils from oxidation in the area of the foil-pin welded joint.
- the welded joints produced by resistance welding between the pin and the foil are manually inserted up to the height into a sand-like medium up to which the chromium plating is to take place.
- the partial chromium deposition By chemical reactions takes place in a less environmentally friendly process, the partial chromium deposition.
- a higher temperature load capacity of the film-pin connections is achieved. In this case, a temperature load up to 550 ° C is possible.
- the oxidation of the film-pin joints is not responsible for the failure of the foil seal, but the attack of the molybdenum foil by the corrosive filling components (for example metal halides) or also filling gases.
- the molybdenum foil is previously sandblasted, resulting in an improvement of the glass-metal compound. Sandblasting, however, results in resistance welding to high rejects, as this non-conductive Al 2 O 3 particles remain on the Mo film surface.
- the wear of the resistance welding electrodes increases very much. In the case of sandblasted foils replacement of the electrode is necessary after approx. 70 welds (compared to a replacement interval of approx. 1000 welds with untreated foil), so that a frequent change of the electrodes is necessary.
- the molybdenum foil is partially or preferably coated on all sides with pure ruthenium or a compound containing ruthenium.
- a coating material is especially pure ruthenium, as well as a molybdenum-ruthenium alloy with eutectic composition.
- the layer thicknesses of the ruthenium-containing layer are preferably in the range of 0.02 to 1.0 ⁇ m. In a particularly preferred embodiment, the layer thickness is 0.02 to 0.09 microns.

- molybdenum foils are very good weldability, in contrast to molybdenum foils, or the like with chromium, silicon, aluminum. are coated.
- the oxidation resistance of the pin-foil welds is increased by coating the current leads with the same or similar coating materials that can be used for the foil.

- the molybdenum foil or the molybdenum foils are provided according to the invention with a ruthenium-containing coating.
- the inner power supply is uncoiled and has a diameter of 10 to 100 .mu.m, in particular 10 to 50 microns.
- the inner power supply is simply coiled and has an outer diameter of 20 to 150 .mu.m, in particular 20 to 80 microns.
- a method for producing an electrically conductive connection between a film of molybdenum and a metal wire, in particular with a diameter between 10 and 100 microns, is characterized in that the film with a ruthenium-containing Coating is provided in the area of the contact surface to the wire.
- the wire is made of tungsten in particular.
- the metal wire may simply be coiled, thus forming a coil.
- the outer diameter of the thread can be between 20 and 80 ⁇ m.
- the preferred exemplary embodiment of the invention shown schematically in FIG. 1 is a high-pressure discharge lamp with an electrical power consumption of approximately 24000 W.
- This lamp has a discharge vessel 1 consisting of quartz glass.
- the discharge vessel 1 has a discharge space 2 and two on top of each other On the opposite sides of the discharge space 2 arranged, cylindrical piston shanks 3, of which in the figure only a partial and cut is shown.
- Two tungsten electrodes 4 each extend from the discharge space 2 into one of the piston shafts 3, where they are each soldered to a circular disk-shaped molybdenum disk 7. With the molybdenum disk 7, four molybdenum foils 5 are welded, which are arranged uniformly along the lateral surface of a hollow quartz glass rod 8.
- the hollow quartz glass rod 8 was introduced into the interior of the hollow piston shaft 3 together with the molybdenum foils 5.
- the molybdenum foils 5 form a gastight seal with the quartz glass of the piston skirt 3 and the quartz glass of the hollow quartz glass rod 8.
- the molybdenum foils 5 melted in the quartz glass have a coating 6 of 75 nm ruthenium.
- the electrode 4 is in the range of the piston shaft 3 wrapped with a molybdenum foil 10, which is not melted in the quartz glass.
- the exemplary embodiment of the invention depicted in FIG. 2 is a high-pressure discharge lamp which is capped on one side.
- This lamp has a quartz glass discharge vessel 9, which is crimped on one side and in which an ionizable filling comprising corrosive metal halides is enclosed in a gas-tight manner.
- two electrodes 22, 23 are arranged, each of which is electrically conductively connected via a molybdenum foil 24, 25 embedded in the pinch seal of the discharge vessel 9 with a respective power supply 26, 27 projecting from the discharge vessel 9.
- the discharge vessel 9 is, at a short distance, completely surrounded by a single-sided squeezed, gas-tight sealed envelope bulb 28.
- the enveloping bulb 28 is made of quartz glass, which is doped with about 0.5 percent by weight of cerium. Within the enveloping piston 28 is nitrogen gas, which has a cold filling pressure between 600 mbar to 700 mbar at room temperature.
- the outgoing from the discharge vessel power supply lines 26, 27 are each electrically connected via a molybdenum foil 29, 30 embedded in the squeezing of the enveloping piston 28, each with a led out of the enveloping bulb 28 power supply 11, 12.
- An unilaterally squeezed and unilaterally socked outer bulb 13 encloses the enveloping bulb 28 gas-tight.
- the outer bulb 13 is evacuated and also consists of a doped with about 0.5 weight percent cerium quartz glass.
- the led out of the enveloping bulb 28 power supply lines 11, 12 are each electrically connected via a molybdenum foil 14, 15 embedded in the pinch seal of the outer bulb 13, each with a current from the outer bulb 13 power supply 16, 17.
- the led out of the outer bulb 13 power supply lines 16, 17 are connected to the protruding from the base 18 pins 19, 20 in electrical contact.
- the molybdenum foils used in this embodiment are all coated with a Mo-Ru eutectic alloy whose thickness is 500 nm.
- the composition is molybdenum 43% by weight, ruthenium 57% by weight (preferably at least 40%, advantageously more than 50% ruthenium).
- the power supply lines 26, 12 and 17 are coated with a Mo-Ru alloy.
- a halogen incandescent lamp 35 (12V at 100 W power) with a lamp bulb 36 made of quartz glass, with Help a pinch seal 37 is gas-tight.
- two molybdenum foils 38 are embedded.
- Within the lamp bulb is a double-spiraled filament 39, the single-turn ends act as an inner power supply 40.
- the inner power supply lines are each welded to one of the embedded in the pinch seal molybdenum foil 38.
- From the pinch seal 37 protrude two outer power supply lines 34, which are connected to one of the two molybdenum foils.
- the two molybdenum foils embedded in the pinch seal are coated on one side with a 90 nm thick Mo-Ru alloy eutectic Mo-Ru alloy on the side to which the power supply 40 is attached.
- the Wendelende 40 consists of 15 microns thick tungsten wire, which is simply coiled. Its outer diameter is 55 ⁇ m. The helical end and the foil are connected together by a brazing process.
- the particular advantage is that hitherto for the resistance welding a powder layer (molybdenum with coarse grain size) had to be used, in which the coil was pressed. When, current passage of the welding process, there were several shunts due to the inhomogeneous powder layer. This led to high rejection and limited the lower limit of the outer diameter of the single-turn power supply to about 80 microns, while according to the invention also corresponding outer diameter between 20 and 60 microns are processed.
- the ruthenium coating thus allows an improved connection between film and power supply, this principle applies both to the inner and the outer power supply. in general, however, the internal power supplies are more critical. Therefore, the ruthenium coating can be applied on one side of the film only in the vicinity of the contact surface of the power supply.
