Replacement of cobalt in Environmental Control System bleed valves

Topic description

Specific Challenge:

The project aims to study new nickel self-fluxing alloys and their elaboration routes for the bleed valves butterfly in replacement of cobalt alloy. This project will help to overcome health potential issues regarding wear particles of cobalt alloys in cabin air, but also the need of a higher wear resistant sealing rings and leakage free valve in new hotter and more pressurized bleed air for the future engines and the future less bleed Environmental Control Systems.
