Master Thesis: »Benchmark: Waterjet- or laser-stripping of ceramic coatings on turbine blades«

Webseite Fraunhofer Institute for Production Technology IPT

The Fraunhofer-Gesellschaft ( currently operates 75 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 29,000 employees work with an annual research budget of 2.8 billion euros.

The lifetime of turbine blades can be extended by renewing ceramic thermal barrier coatings. Current stripping processes of these coatings are labor-intensive and are using hazardous chemicals. Waterjet- and Laser-Stripping provide a green alternative for coating removal on high-performance parts of a turbomachine engine even on complex geometries. A Technological Benchmark of two competing process technologies for coating removals on complex geometries is required to obtain its future potential.

What you will do
Technological Benchmark of both laser- and waterjet technologies for coating removals on complex geometries (stripping efficiency and quality):

  • Process parameter study on test geometry (2D)
  • Process design in 3D (CAM)
  • Turbine blade stripping trial
  • Analysis and evaluation of results

What you bring to the table

  • You are studying engineering, physics, or a comparable subject
  • You have a profound interest in practical experiments
  • A high degree of initiative and responsibility

What you can expect

  • Ideal conditions for practical experience alongside your studies
  • Professional supervision and collaboration in a dedicated team
  • A state-of-the-art machine park equipped with edge cloud systems and 5G infrastructure
  • Flexible working to combine study and job in the best possible way
