Flying metal!

Imagine a bulk of metal (titanium, zirconium and nickel) at 1100ºC flowing from a crucible and getting in contact with a cold fast spinning wheel. In principle, it sounds like a bad idea. And it is also the way the team lead by Dr. Laurent Marot produces amorphous metallic ribbons. Their main areas of application are transformer cores and active solder foils.

The company Endress+Hauser came to the University of Basel, looking for a solder foil that met its requirements. Basel University developed and is still improving this production method, reaching high levels of quality and reducing the process energy cost. According to Laurent Marot: “The cooperation is beneficial for both sides. Endress Hauser gets high-quality metallic glasses that they can use in their production of pressure sensors, and the university can use the revenue to finance their research. “

We did this picture, supervised by Dr. Laurent Marot to illustrate the process.
