Method and device for thermal spraying of coating materials
The method comprises melting a coating material, which is present in the form of spray wire, and thermally spraying the coating material by an atomizing gas and/or combustion gas. The melted coating material is displaced by coupling of ultrasound in vibrations during melting. The ultrasound is direc...

| description | The method comprises melting a coating material, which is present in the form of spray wire, and thermally spraying the coating material by an atomizing gas and/or combustion gas. The melted coating material is displaced by coupling of ultrasound in vibrations during melting. The ultrasound is directly coupled to the coating material in which: an ultrasonic generator (6) is brought in direct contact with the melted coating material; and an ultrasound is formed by a modulation or pulse-like variation of the current of the power supply. The method comprises melting a coating material, which is present in the form of spray wire, and thermally spraying the coating material by an atomizing gas and/or combustion gas. The melted coating material is displaced by coupling of ultrasound in vibrations during melting. The ultrasound is directly coupled to the coating material in which: an ultrasonic generator (6) is brought in direct contact with the melted coating material; and an ultrasound is formed by a modulation or pulse-like variation of the current of the power supply and by a modulation or pulse-like variation of an atomizing gas- and/or combustion gas-gas stream, where: the current changes its direction; the current direction change is carried out within ten seconds to pico seconds; and a current strength is 0.01-3000 Å . The ultrasound is indirectly coupled to the coating material in which: an ultrasonic generator is brought in contact with the melted coating material via a wire guide; and an ultrasonic generator is arranged in a gas stream of the atomizer- and/or combustion gas in a flow direction or a nozzle is designed as the ultrasonic generator, which couples the ultrasound indirectly via the gas stream into the melted coating material. The ultrasound is present in a frequency range of 15 kHz to 10 MHz. The thermal spraying step is carried out by a wire flame spraying and an electric arc. The atomizing gas is preheated to increase the temperature during arc spraying process. An independent claim is included for a device for thermal spraying of coating materials.
