Abstract

Die Erfindung betrifft einen Innenbrenner zum Lichtbogendrahtspritzen von Hohlräumen, insbesondere von Zylinderlaufflächen. Der Innenbrenner weist mindestens zwei Brennerrohre (3) zur Zuführung von Elektroden auf. Die Elektroden sind zur Aufschmelzung vorgesehen und als in einem Lichtbogen abbrennbare Drähte ausgebildet. Der Innenbrenner weist ferner eine Gaszuführung (1) für ein Prozessgas auf, welches zum Transport und Zerstäuben des aufgeschmolzenen Drahtmaterials in Richtung der zu beschichtenden Oberfläche des Hohlraumes vorgesehen ist. Die Drähte sind durch die Brennerrohre austrittsseitig und im Bereich des Lichtbogens aufeinander zu geführt, wobei der im Berührungsbereich der Drähte angeordnete Lichtbogen der Elektroden-Drähte im Bereich des Gasstromes des ausgetretenen Prozessgases angeordnet ist, und wobei der Gasstrom des ausgetretenen Prozessgases, im folgenden vereinfachen Hauptgasrichtung genannt, quer zur Haupttransportrichtung der Drähte angeordnet ist. Des weiteren sind die Drähte außer aufeinander zu noch zusätzlich quer dazu gebogen.

The invention relates to an internal burner for the arc wire spraying of cavities, in particular of cylinder running surfaces. The internal burner has at least two burner tubes (3) for the supply of electrodes. The electrodes are intended for melting and designed as burnable in an arc wires. The inner burner also has a gas supply (1) for a process gas, which is provided for transporting and atomizing the molten wire material in the direction of the surface of the cavity to be coated. The wires are guided towards one another through the burner tubes on the outlet side and in the region of the arc, wherein the arc of the electrode wires arranged in the contact region of the wires is arranged in the region of the gas stream of the leaked process gas, and wherein the gas flow of the leaked process gas simplifies the main gas direction called, is arranged transversely to the main transport direction of the wires. Furthermore, the wires are bent in addition to each other additionally transversely thereto.
