Details of the research project
Laser absorption spectroscopy in the infrared spectral range is a suitable method for the optical process control of plasma nitriding. Conventional spectroscopy systems would be too complex and expensive to use in industrial plasma nitriding, as many laser sources would be required to measure the process-relevant gas and molecule concentrations. With the help of an optical frequency comb, which replaces many thousands of lasers, concentrations of these species can be detected simultaneously and made available to a process control system. However, the conditions in industrial plasma nitriding have stringent requirements in terms of compactness, robustness and resolution power, among other things. New techniques and innovative components of a frequency comb-based spectroscopy system required for this process will be developed within the framework of the InPro-F joint project.
In the joint project, the SMEs Menlo Systems GmbH and neoplas control GmbH will carry out the necessary developments together with the Leibniz Institute for Plasma Research and Technology e. V. as an academic partner. The company RUBIG GmbH & Co. KG, as a leading manufacturer of nitriding plants, will formulate the corresponding requirements, accompany the developments and provide both the industrial expertise and nitriding plants for development, testing and verification.
The project goal is to demonstrate a compact and robust frequency comb system that can be used in industrial plasma nitriding processes, which will allow in-situ process control, thus making it possible to realise the commercial and ecological savings potential of this process. A new sales market with long-term growth potential will open up for the SMEs, and the associated partner will be able to consolidate its market leadership.
