Innovative energy technologies in many cases require processes at temperatures above 800 °C. This places special demands on the materials and components to be used. Therefore, for more than 15 years, the scientists of our teaching and research area Research Group have been developing and modifying laser technologies that enable the use of different materials under the conditions of high temperature and special environmental conditions. In each case, laser-based technologies for joining, coatings and surface structuring are developed and applied for this purpose.
We are active in the following areas:
- Development and testing of laser-based soldering technologies for high-temperature resistant joining of ceramic-to-ceramic or ceramic-to-metal joints. The special features of the process, local energy input and short process times are used to advantage.
- Development of high-temperature brazing alloys for use under special environmental conditions. The development includes the group of metallic active solders as well as glass-ceramic solders.
- Development of a laser-assisted coating technology (PLD process) for producing ultra-dense, chemically precisely defined ceramic coatings. These can be used, for example, for the long-term stable, safe confinement of radioactive fission products as well as for the protection of surfaces against corrosion and abrasion.
- Laser-based structuring of ceramic surfaces to increase the specific surface area and/or to adjust special surface properties.
Another focus of our work is the development of resource-saving technologies for the dismantling of nuclear power plants. Laser-based technologies can make an important contribution to this, and we are establishing these personnel- and resource-saving processes in practice as efficient alternatives to conventional methods.
Our main areas of work are:
- Development and testing of innovative procedures for laser-based decontamination of radioactively or chemically-toxically contaminated surfaces. These methods represent a personnel- and resource-saving alternative to conventional, mechanical decontamination technologies.
- Development of a method for laser-based sampling in concrete boreholes for in-situ analysis.
- Laser-based cleaning of various surfaces to remove oxide layers, for example.
The research group has access to a state-of-the-art laboratory equipped with powerful lasers of different wavelengths and working modes as well as the corresponding peripheral equipment for its research work.
