REWITEC® on the 2-disc test bench

The Centre of Excellence for Tribology at the University of Mannheim used the two-disc test rig to investigate the friction and wear behaviour of materials and coatings, as well as the properties of lubricants under rolling and rolling-contact loads. Thanks to this state-of-the-art testing method, data (e.g. friction torque) can be recorded continuously in digital form. Furthermore, it is possible to determine mass-based wear by weighing.

Scientific study using Castrol X320

• The red graph is without REWITEC^®
• The blue graph is from REWITEC^® added after about 20 hours
• The green graph is by REWITEC^® from the very beginning
• Up to 46% less surface roughness
• Up to 22% less frictional force

Scientific study using AGIP SX320

REWITEC coating: a before-and-after comparison – SEM images following the long-term test

The studies confirm:

20 % lower temperature
in gearboxes and bearings*

33 % less friction
in gearboxes and bearings*

50 % less roughness
on metal surfaces*

* Data based on rolling wear tests carried out on the 2disc test rig at the Tribology Centre of Excellence at Mannheim University of Applied Sciences in September 2012
