Applied Research at BFH - ALPS

For applications in the field of cutting tools (Microoutils, lead-free brass machining) or watchmaking industry (small surface contacts) there is a need to develop new solutions in order to improve the lifetime and tribological performances of the components. First promising results from a collaboration between the (Berner Fachhochschule) BFH and the (Haute Ecole ARC) HE-ARC, have been obtained on nanotextured carbon thin films by high power pulsed laser.
