Reciprocating Sliding Friction and Wear test
Friction and wear are two important factors affecting mechanical components' performance and durability. Reciprocating sliding friction and wear tests evaluate the tribological properties of materials and coatings under simulated sliding conditions. These tests can provide valuable information on the wear...
Superlubricity: The energy saving superhero for new products
The article is sponsored by Bruker. Friction is the great obstacle to overcome when testing new products with moving parts. While friction can never disappear completely, it may be possible to achieve ultralow friction: a state called superlubricity, where the...
Estimation of functional properties of coatings by different tribological test methods
By Dr. Ameneh Schneider – Optimol Instruments GmbH and Dr. Mathias Woydt – MATRILUB Introduction Interest in special coatings and thin films for tribological applications increased rapidly in the last few decades, especially driven by the automotive industry [1,2]. Specific...
Beware of triboelectricity! But it’s ok, there are solutions
What is the link between a grain silo, a nylon sleeping bag and a flying helicopter? They can all accumulate triboelectric charges! The charges accumulate because the materials in relative motion are insulating materials (respectively grain against grain, nylon against...
Tribometer managing autumn leaf problem on railways worldwide
Since the 1800s, railway organizations have been struggling with low adhesion on the rail, especially during the Autumn season also known as the “slippery track season”. In Autumn, leaves fall on the rails and when train wheels crush the leaves,...
