Abstract
The present technology relates to a method for coating a workpiece, in which a material is applied to the workpiece via a thermal spraying process that is monitored and evaluated to establish on-line process control. According to certain embodiments of the presently described method, infrared emissions of a spray jet are detected with the aid of at least one infrared camera, and properties of the spray jet are determined by analyzing the infrared emissions of the spray jet, which are detected by the at least one infrared camera.
Claims10
A method of establishing online process control for the coating of a workpiece via a sputtering process comprising the steps of:
- applying at least one coating material to at least one workpiece by at least one spray jet;
- detecting and recording at least two infrared emissions of at least two different molecules, atoms, or a combination thereof emitted from the at least one spray jet by at least one infrared camera using at least two different infrared filters;
- and
- analyzing the recorded infrared emissions to determine the properties of the coating material emitted.
