<p>Thermally coating using a material stream and a nozzle, preferably using a powder stream, comprises heating and melting a material of the material stream by plasma or flame. The material is discharged from the nozzle or is injected at the end of the nozzle based on at least one target variable, preferably material flow speed of the material stream, brightness distribution of the material stream, temperature distribution and/or voltage between an electrode and the nozzle. The changes in the target variables are determined, which are used for controlling the target variables in the coating. Thermally coating using a material stream and a nozzle, preferably using a powder stream, comprises heating and melting a material of the material stream by plasma or flame. The material is discharged from the nozzle or is injected at the end of the nozzle based on at least one target variable, preferably material flow speed of the material stream, brightness distribution of the material stream, temperature distribution and/or voltage between an electrode and the nozzle. The power of the nozzle is measurable and controllable. The desired optimal target sizes are achieved and/or maintained starting from at least one optimal initial value of controlled variables, before coating. The method allows the adjustment of parameter sets for different configurations e.g. higher-, lower- and constant control variables. The changes in the target variables are determined, which are used for controlling the target variables in the coating.</p> |
