Capability Summary

ORNL researchers are performing cutting-edge research to understand wear in a variety of systems using multiple classes of materials. This process includes comprehensive tribosystem analysis for understanding failure modes and wear mechanisms based on contact interface mechanical, thermal, and lubrication modeling and worn surface examination. Research seeks innovative solutions through development and application of advanced coatings and lubricants. The effort features well-equipped tribological testing facilities for various wear modes in controlled conditions and state-of-the-art materials characterization.

Equipment & Facilities

More than 15 tribometers operating under various wear modes including abrasion (two-body and three-body), sliding wear, rolling contact fatigue, and fretting in both dry and lubricated conditions in ambient and controlled environments

Surface topographical, mechanical, energy, morphological and compositional characterization  

Lubricant rheological, thermal and electrical analysis

Coatings and surface treatments using chemical vapor deposition (CVD) and plasma/corona treatment

Nanomaterials synthesis and surface functionalization
