Description

Verfahren und Vorrichtung zum thermischen Spritzen zur Beschichtung von Oberflächen Method and device for thermal spraying for coating surfaces
Die Erfindung richtet sich auf ein Verfahren und eine Vorrichtung zum thermischen Spritzen insbesondere von Metallen, zur Beschichtung von Oberflächen, wobei das zur Beschichtung herangezogene Material in Form eines Drahtes zugeführt, aufgeschmolzen und verspritzt wird.The invention relates to a method and a device for thermal spraying, in particular of metals, for coating surfaces, the material used for the coating being supplied, melted and sprayed in the form of a wire.
Derartige Vorrichtungen sind in unterschiedlichen Ausführungen bekannt. So sind beispielsweise von Hand zu betätigende Spritzpistolen bekannt, bei denen zwei Drähte über Vorschubeinrichtungen im Winkel zueinander vor einer Zerstäubergasdüse zusammengeführt werden, wobei zwischen den Drahtspitzen ein die Drähte aufschmelzender Lichtbogen erzeugt wird.Such devices are known in different designs. For example, hand-operated spray guns are known in which two wires are brought together at an angle to one another in front of an atomizing gas nozzle via feed devices, an arc melting the wires being generated between the wire tips.
Es ist auch bekannt, im Spritzkopf eine Schmelzflamme zu erzeugen, mit deren Hilfe das aufzusprühende Gut aufgeschmolzen wird, wobei dann über Druckluft oder dergleichen die aufgeschmolzenen Partikel auf die zu beschichtende Oberfläche gefördert werden. Lediglich als Beispiel sei für eine Lichtbogentechnologie die EP-0 239 585-B genannt mit weiteren Literaturhinweisen.It is also known to generate a melting flame in the spray head, with the aid of which the material to be sprayed on is melted, the melted particles then being conveyed onto the surface to be coated using compressed air or the like. EP-0 239 585-B with further references is mentioned only as an example of an arc technology.
Aufgabe der Erfindung ist die Schaffung eines Verfahrens und einer Vorrichtung zum Verspritzen von metallischem Draht ohne Zerstörung wenigstens einer der Elektroden. Dabei sollen ein hoher Wirkungsgrad, ein geringer Geräuschpegel und eine leichte Handhabung gewährleistet sein. Mit dem Verfahren und der Vorrichtung der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, dass die Aufschmelzenergie durch einen Plasmalichtbogen erzeugt wird, wobei der Lichtbogen zwischen einer nicht abschmelzenden, feststehenden Elektrode und einer abschmelzenden Elektrode in Form des Drahtes brennt, und das aufgeschmolzene Material in Drahtlaufrichtung verspritzt wird.The object of the invention is to provide a method and a device for spraying metallic wire without destroying at least one of the electrodes. A high level of efficiency, a low noise level and easy handling should be guaranteed. With the method and the device of the type described in the introduction, this object is achieved according to the invention in that the melting energy is generated by a plasma arc, the arc burning between a non-melting, fixed electrode and a melting electrode in the form of the wire, and that melted material is sprayed in the wire running direction.
Brennköpfe mit einem Plasmalichtbogen sind für sich gesehen bekannt als zum Schneiden von Metallblechen einzusetzende Schneidköpfe, die mit Druckluft arbeiten. Bei diesem Lichtbogen-Plasmaschneiden wird die Wäremenergie und die kinetische Energie einer ioinisierten Gassäule (Plasma) genutzt, um das Metall zu schmelzen und aus der Schnittfuge zu verdrängen. Diese Eigenschaft macht sich die Erfindung zunutze, indem der Plasmalichtbogen ein Druckluft-Plasmalichtbogen ist und einem solchen Plasmaschneidkopf ein Draht zur Zerstäubung zugeführt wird. Vorzugsweise brennt dabei der Lichtbogen zwischen einer nicht abschmelzenden, feststehenden Elektrode und einem abschmelzenden Draht. Das aufgeschmolzene Material wird in Drahtlaufrichtung verspritzt. Der Plasmalichtbogen wird zunächst zwischen den beiden Elektroden gezündet. Dabei übernimmt ein elektrisch leitender Draht die Funktion einer Elektrode. Nach der Zündung wird der sich verbrauchende Draht nachgeführt.Burning heads with a plasma arc are known per se as cutting heads to be used for cutting metal sheets, which work with compressed air. With this arc plasma cutting, the thermal energy and the kinetic energy of an ioinized gas column (plasma) are used to melt the metal and displace it from the kerf. The invention makes use of this property in that the plasma arc is a compressed air plasma arc and a wire for atomization is fed to such a plasma cutting head. The arc preferably burns between a non-melting, fixed electrode and a melting wire. The melted material is sprayed in the wire running direction. The plasma arc is first ignited between the two electrodes. An electrically conductive wire acts as an electrode. After the ignition, the consumed wire is fed.
Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen, wobei insbesondere, wie oben schon angedeutet, vorgesehen sein kann, dass der Brennkopf als Druckluft-Plasmalichtbogen-Brenner ausgebildet ist. Die Zuführdüse des Drahtes mit dem Zerstäubergas ist dabei zweckmäßig im Winkel zur Mittelachse des Plasmabrenners angeordnet, wobei beispielsweise der Winkel in weiterer Ausgestaltung zwischen Drahtzufuhr und Plasmabrenner-Mittelachse etwa 75° beträgt. Zweckmäßig umgibt die Zerstäubergasdüse die zentrische Drahtzufϊihr ringförmig.Embodiments of the invention emerge from the subclaims, and in particular, as already indicated above, it can be provided that the burner head is designed as a compressed air plasma arc burner. The feed nozzle of the wire with the atomizing gas is expediently arranged at an angle to the central axis of the plasma torch, the angle between the wire feed and the plasma torch central axis being approximately 75 °, for example. The atomizing gas nozzle expediently surrounds the central wire feed in a ring.
Vorteilhaft kann es sein, wenn ein Inertgas-Plasmabrenner der Zerstäubergasdüse zugeordnet ist und/oder dass ein nicht metallischer Draht zur Aufschmelzung und zum Verspritzen der Zerstäubergasdüse zugeordnet werden kann.It may be advantageous if an inert gas plasma torch is assigned to the atomizing gas nozzle and / or that a non-metallic wire can be assigned to the atomizing gas nozzle for melting and spraying.
Der besondere Vorteil der Erfindung besteht unter anderem darin, dass eine höhere Abschmelzleistung erbracht werden kann, die Auftragseffizienz lässt sich um wenigstens 10% erhöhen, wobei die Staubbildung sowie die Materialverdampfung reduziert werden.The particular advantage of the invention is, inter alia, that a higher melting rate can be achieved, the application efficiency can be increased by at least 10%, the dust formation and the material evaporation being reduced.
Je nach Einsatz der erfindungsgemäßen Vorrichtung kann in weiterer Ausgestaltung vorgesehen sein, dass wenigstens zwei Brennköpfe mit zugeordneten Drahtzufiihr- und Zerstäubergasdüsen vorgesehen sind, Dabei ist es möglich, unterschiedliche Materialien den unterschiedlichen Brennköpfen zuzuführen und das Materialgemisch dann auf die zu beschichtende Oberfläche aufzubringen.Depending on the use of the device according to the invention, it can be provided in a further embodiment that at least two burner heads with associated wire feed and atomizing gas nozzles are provided. It is possible to feed different materials to the different burner heads and then to apply the material mixture to the surface to be coated.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung. Diese zeigt inFurther details, advantages and features of the invention result from the following description and from the drawing. This shows in
Fig. 1. eine vereinfachte Wiedergabe einer Vorrichtung nach der Erfindung sowie inFig. 1. A simplified representation of a device according to the invention and in
Fig.2 eine vergrößerte Schnittdarstellung der Kopfausbildung der erfindungsgemäßen Vorrichtung.2 shows an enlarged sectional view of the head configuration of the device according to the invention.
Die allgemein mit 1 bezeichnete Vorrichtung besteht aus einem Spritzpistolengehäuse 2 mit einem Handgriff 3 als Betätigungsschalter 4, wobei dem Gehäuse 2 ein Spritzdrahtzuführkopf 5 und ein Druckluft-Plasmabrennkopf 6 zugeordnet ist, deren Mittelachsen zueinander im dargestellten Beispiel einen Winkel von 75° einnehmen. Dem Plasmabrennkopf 6 ist ein lediglich angedeutetes Schlauchpaket 7 zugeordnet mit Stromzuführung und Druckluftzuführung, während dem Drahtzuführkopf ein Zuführschlauch 8 für den mit 9 bezeichneten Draht zugeordnet ist. Die Druckluftzufuhr erfolgt über das Gehäuse 2, wie sich insbesondere aus Fig. 2 ergibt.The device, generally designated 1, consists of a spray gun housing 2 with a handle 3 as an actuation switch 4, the housing 2 being associated with a spray wire feed head 5 and a compressed air plasma burning head 6, whose In the example shown, central axes form an angle of 75 ° to one another. The plasma burning head 6 is assigned a hose package 7, only indicated, with a power supply and compressed air supply, while a supply hose 8 for the wire designated 9 is assigned to the wire feed head. The compressed air is supplied via the housing 2, as can be seen in particular from FIG. 2.
Der Draht 9 tritt vorne aus der mit 10 bezeichneten Zerstäubergasdüse aus und wird in einem mit 11 bezeichneten Plasmalichtbogen aufgeschmolzen und mittels des Zerstäubergases als Spritzstrahl 12 auf eine nicht dargestellte Oberfläche geworfen.The wire 9 emerges from the front of the atomizing gas nozzle denoted by 10 and is melted in a plasma arc denoted by 11 and thrown onto a surface (not shown) by means of the atomizing gas as a spray jet 12.
In Fig. 2 ist der aufzuschmelzende Draht selbst nicht dargestellt, lediglich ein Drahtführungskanal 13, der die Zerstäubergasdüse 10 zentrisch durchsetzt. Das Zerstäubergas wird über das Gehäuse 2 über entsprechende Kanäle 14 einer Ringkammer 15 zugeführt, die ihrerseits im wesentlichen zentrisch den Zuführkanal 13 für den Draht umgibt. Im Plasmabrennkopf 6 befindet sich eine Elektrode 16 mit einem Zr/Hf-Einsatz 17, wobei auch hier eine zentrische Druckluftzuführung 18 vorgesehen ist, die von Isolierelementen 19 umgeben ist.In Fig. 2, the wire to be melted itself is not shown, just a wire guide channel 13 which passes through the atomizing gas nozzle 10 centrally. The atomizing gas is supplied via the housing 2 via appropriate channels 14 to an annular chamber 15 which in turn surrounds the feed channel 13 for the wire essentially centrally. An electrode 16 with a Zr / Hf insert 17 is located in the plasma burning head 6, a central compressed air supply 18 being provided here as well, which is surrounded by insulating elements 19.
Nicht näher dargestellt sind Regeleinrichtungen, die beispielsweise dafür sorgen, dass die Druckluftzufuhr für den Plasmabrenner 6 und die Druckluftzufuhr für die Ausbildung des Zerstäubergasstrahles unterschiedlich eingestellt werden kann.Control devices are not shown, which ensure, for example, that the compressed air supply for the plasma torch 6 and the compressed air supply for the formation of the atomizing gas jet can be set differently.
Natürlich ist das beschriebene Ausführungsbeispiel der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So kann, statt wie dargestellt, der Lichtbogen nicht nur zwischen dem Brenner als Kathode und beispielsweise dem Spritzdraht als Anode ausgebildet werden, es kann auch der Lichtbogen innerhalb des Brenners zwischen einer Kathode und einer Anode ausgebildet werden, wobei dann auch elektrisch nicht leitende Drähte, z.B. kunststoffummantelte Oxidpulverfülldrähte verarbeitet werden können. Diese Ausführungsform macht die Vorrichtung flexibler in der Verarbeitung von verschiedenen Werkstoffen. Of course, the described embodiment of the invention can be modified in many ways without departing from the basic idea. Thus, instead of as shown, the arc can not only be formed between the burner as a cathode and, for example, the spray wire as an anode, the arc can also be formed within the burner between a cathode and an anode, with electrically non-conductive wires e.g. plastic-coated oxide powder cored wires can be processed. This embodiment makes the device more flexible in the processing of different materials.
