Abstract

Die Erfindung betrifft ein Verfahren zur Innenbeschichtung eines Waffenrohres (1), auf dessen innere Oberfläche (2) zur Vermeidung von Erosionen mindestens in einem Teilbereich (4) mindestens eine aus einem Werkstoff mit hohem Schmelzpunkt bestehende Deckschicht (3) durch Elektroplattieren aufgebracht wird.The invention relates to a method for coating the inside of a weapon barrel (1) its inner surface (2) to avoid erosion at least in a partial area (4) at least one made of a high melting point material Cover layer (3) is applied by electroplating.

Um das Waffenrohr (1) mit einer Innenbeschichtung zu versehen, mit der erreicht wird, daß die Rohrerosionen geringer sind als bei vergleichbaren Waffenrohren, schlägt die Erfindung vor, daß vor dem Aufbringen der Deckschicht (3) mindestens eine Zwischenschicht (5) durch Sprengplattieren auf die innere Oberfläche (2) des Waffenrohres (1) aufgebracht wird, die aus einem Werkstoff besteht, der eine Wärmeleitung besitzt, welche größer ist als die Wärmeleitung des Waffenrohres (1), und der eine Duktilität aufweist, die größer ist als die Duktilität der Deckschicht (3).

Figure 00000001
In order to provide the weapon barrel (1) with an inner coating which ensures that the tube erosions are lower than in comparable weapon barrels, the invention proposes that at least one intermediate layer (5) be applied by explosive plating before the cover layer (3) is applied the inner surface (2) of the gun barrel (1) is applied, which consists of a material which has a heat conduction which is greater than the heat conduction of the gun barrel (1) and which has a ductility which is greater than the ductility of the Top layer (3).
