Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
