The hybrid metal/ceramic material TiSurf® for aerospace applications: a preliminary study

Purpose and goal

The overall aim of the project was to evaluate the industrial potential of TiSurf, a ceramic/metal hybrid material developed by NewSoTech, for aero engine applications. A Tisurf® material was characterized through 4-points bending fatigue at room temperature and oxidation tests (500, 593 and 700oC for 10 min, 1h, 10h, 100h, 500h). All the planned tests were performed, revealing useful information on TiSurf®. Nevertheless, further characterizations and testing are necessary to fully understand TiSurf® behavior and its possible applications in aero engines.

Expected results and effects

This project provided initial information on Tisurf® behavior under specific test conditions, which were determined by possible aero engine applications for Ti alloys with improved surface properties. It revealed both the potential and the limitations of Tisurf® for aerospace applications. The developer of TiSurf®, NewSoTech, can adapt the knowledge gained from this project in order to proceed with additional process optimizations required for becoming a qualified material supplier in the future.

Planned approach and implementation

This project is based on a collaboration between NewSoTech, the Swedish owner of TiSurf®, RISE IVF, Linköping University and University West in order to combine the strengths and knowledge of different actors through the involvement of experts in process development, materials, characterizations and testing. The project also benefitted from the active participation of GKN, providing useful input on possible applications for TiSurf® in aero engine applications, aiding the selection of experimental tests and conditions.
