High Speed-PVD XAlON oxidation protection coatings for gamma-TiAl alloys

• Applicant: Professorin Dr.-Ing. Kirsten Bobzin
• Subject Area: Coating and Surface Technology
• Term: from 2013 to 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 249455605

The aim of this research project is the investigation of amorphous Oxi-Nitride coatings as oxidation protection coatings for gamma-TiAl alloys. The scientific goal is to find out, whether such coatings can provide oxidation protection, so that the application temperature of these alloys can be increased beyond 900 °C. For the application of the coatings a new coating technology, the so called High Speed-PVD technology will be used. This technology enables deposition rates up to 100 micrometers per hour, which is not possible withestablished thin film technologies.
