Tribology

Polymer composites are crucial to reducing friction and wear in many technical components. Our main goal is therefore to advance the art of designing materials with tailored friction and wear.

The key challenge for this is to understand the complex interaction of material composition, manufacturing, operating conditions and failure mechanisms. In tribometry we emphasize the development of new test procedures and tribometers for improved data quality and increased data amount,  both of which are critically needed for the design of tribological materials.

In fundamental material research we focus on the formation and stability of transfer films in polymer-metal sliding and their impact on friction and wear. We characterize and evaluate composite materials using in-house designed and constructed model and component test rigs equipped with precision sensors.

These high performance composites are typically applied as e.g. slide bearings with high thermal stability, low friction coefficient, and extended service life.

They are able to operate under dry, boundary, and hydrodynamic lubrication conditions. Tribology’s close networking with related competence fields enables IVW to offer research and development of tribologic composites along the entire value-added chain. This includes manufacturing processes, testing technology and methodology, and material analytics from a single source.
