Abstract: The invention relates to an apparatus for coating a substrate with a plasma arc torch, and with such a plasma arc torch the powdery additive is to be heated, melted open and accelerated towards the surface with plasma gas generated in the plasma arc torch, and with an additional laser beam. In the plasma arc torch, an annular cathode is located or a plurality of individual cathodes are arranged about a longitudinal axis. Gas is supplied into a plasma space which is located between such an annular cathode or the plurality of cathodes, and such an annular anode. With the invention, coating is to be allowed to be formed with a higher speed and deposition rate, respectively, with respect to the conventional solution with the same and increased quality, respectively, and the directional independence for the formation of the coating is to be ensured.
