ABSTRACT:
A method is proposed for arc spraying by means of a spray gun (1). The spray gun includes two electrically conductive spray wires (2) and at least one first supply device (3) for supplying a fluid (4), with an electrical voltage being applied to the spray wires (2), the spray wires (2) being fed by means of a wire guide (5), an arc (6) being ignited by the electrical voltage, the spray wires (2) being converted into a melt (8) in a melting region (7) and the melt (8) being applied by the fluid (4) to the surface (9) of a body (10). In this connection, particles (11) from a storage container (12) are supplied to the melt (8) by the fluid (4).
