Dry lubricated Harmonic Drives for space applications (HarmLES)
Date du début: 1 juin 2011, Date de fin: 28 févr. 2015,
On spacecrafts reduction of mass and power consumption are a major issue. On the other hand, in case of mechanisms for Solar Arrays or antennas big masses have to be moved and kept in position for long times. Harmonic Drives would fulfil the requirements: high gear ratios enable the use of small actuator motors (low mass and power), they provide high stiffness and high precision even at very low s ...

Development of wear resistant coatings based on complex metallic alloys for functional applications (appliCMA)
Date du début: 1 déc. 2008, Date de fin: 30 nov. 2011,
The project aims at the development of a new type of coatings based on Complex Metallic Alloys (CMA). This is a family of ternary and quaternary alloys which exhibit unexpected properties. The CMAs “Al61.5Cu25.3Fe12.2 B1” and “Al59.5Cu25.3Fe12.2 B3” consist only of metals, which show not metallic- but ceramic-like behaviour. Moreover, the bulk versions of these quasicrystals have proven outstandin ...
