Abstract: A monitoring device (14) and a method for monitoring spray coating of a component by a spraying device (1) including a spray nozzle (3) movable along a specific path in relation to a component surface to be coated. The device has: an input interface (15) for inputting geometry data representative of the geometry of the component surface; a path data recording device (17) for time-resolved recording of path data of the spray nozzle (3) in relation to the component surface; a process data recording device (19) for time-resolved recording of process data of the coating process using the spray nozzle (3); a simulation unit (21) connected to the input interface (15) for receiving the data, for simulating application of the spray coating to the component surface on the basis of the data recorded; and a deviation calculation unit (23), connected to the simulation unit (21), for receiving simulation data and calculating a deviation of the simulated coating from the desired coating.

Abstract: A spray nozzle for atmospheric plasma spraying is provided. The nozzle includes an attachment at an axial end of the spray nozzle from which a protective gas may be discharged in the outflow direction. By means of a plasma spray nozzle that enables atmospheric plasma spraying using protective gas, it is also possible to deposit oxidation-sensitive metal coatings in atmosphere.
