NISSCO

The main problem is that stainless steels used in space do not offer appropriate resistance to fretting (launch vibrations in HDRMs) and that they also cause a strongly reduced life time of solid lubricating coatings in gear applications as in e.g. HARMONIC GEAR® DRIVEs.

The objective is to optimise/develop a surface treatment process towards improvement of those performances by surface treatments (like Nitriding) and to consider optimum performance of solid lubricant coatings on top of them.

The project will cover two issues. In the first half of the project the optimisation of surface treatments is done parallel with an upgrade of a prototype test device "FRESSCO" towards full operability. In second part, optimised process variants will be coated with solid lubricant coatings and tested via FRESSCO towards applications. AAC is known as an expert consultant in both and HMWELSER is intended to become a new Austrian supplier for surface treatments
