Abstract
Auf einer Zündbrücke ist eine reaktive Schicht aufgebracht, die erfindungsgemäß aus einem brennbaren Metall (6) oder aus einem Metall (6), das bei Legierung mit dem Metall (7) der Zündbrücke Energie freisetzt, besteht. Die reaktive Schicht kann als Strich (6) oder in Form von Inseln aufgebracht sein. Als brennbares Metall (6) kommen Zirkonium, Titan, Hafnium, Niob, Tantal, Aluminium und Nickel, gegebenenfalls mit Zündverstärker, in Frage. Um Energie beim Legieren freizusetzen, kann die Zündbrücke aus Platin oder Platinmetallen und das reaktive Metall (6) aus Aluminium bestehen. A reactive layer is applied to an ignition bridge, which according to the invention consists of a combustible metal (6) or of a metal (6) which releases energy when alloyed with the metal (7) of the ignition bridge. The reactive layer can be applied as a line (6) or in the form of islands. The combustible metal (6) is zirconium, titanium, hafnium, niobium, tantalum, aluminum and nickel, optionally with an ignition amplifier. To release energy when alloying, the ignition bridge can be made of platinum or platinum metals and the reactive metal (6) can be made of aluminum.
