Description

Verfahren zum Färben von Gewehrläufen aus nichtrostenden Materialien. Die aus gewöhnlichem Stahl bestehenden Gewehrläufe wurden bisher in der Weise geschwärzt, daß auf der Oberfläche eine dünne Schicht von schwarzem Eisenoxyduloxyd hervorgebracht wurde. Bei Anwendung nichtrostender Materialien, insbesondere der neuen Spezialstähle, ist dieses Verfahren nicht anwendbar, weil auf solchen Stoffen die Bildung der die Farbe bedingenden Oxydschicht nicht möglich ist.Process for dyeing gun barrels made of stainless materials. The gun barrels, made of ordinary steel, have hitherto been blackened in such a way that that on the surface a thin layer of black iron oxide was produced became. When using stainless materials, especially the new special steels, this procedure is not applicable because the formation of the Color-causing oxide layer is not possible.

Es ist Gegenstand der vorliegenden Erfindung, auch bei solchen Gewehrläufen eine Färbung zu ermöglichen, und zwar dadurch, daß die Läufe durch das Spritzverfahren mit einem Metall überzogen werden, dessen Färbung in bekannter Weise durchführbar ist. Man kann zu diesem Zwecke beispielsweise Eisen aufspritzen und dann die Färbung nach dem Rostverfahren in der bisher bekannten Weise durchführen.It is the subject of the present invention, even with such gun barrels to enable coloring by the fact that the runs through the spraying process be coated with a metal, the coloring of which can be carried out in a known manner is. For this purpose, for example, iron can be sprayed on and then the coloring perform according to the rusting method in the previously known manner.

Die Anwendung des Spritzverfahrens bietet dabei den besonderen Vorteil, daß man die Schicht so stark wählen kann, daß nachher eine mechanische Bearbeitung möglich ist, durch die das gewünschte Maß erhalten wird.The use of the spraying process offers the particular advantage that you can choose the layer so strong that a mechanical treatment afterwards is possible, through which the desired dimension is obtained.
