Minimizing Friction and Wear: How Superlubricity Coating can Prevent Economic Losses.

Scientists at Oak Ridge National Laboratory (ORNL) have created a new coating that could significantly reduce friction in load-bearing systems used in a range of devices, including turbines and vehicle drivetrains. Developed by the lab’s tribology group, the coating uses carbon nanotubes to create superlubricity, a property whereby surfaces show almost no resistance to sliding, leading to a coefficient of friction less than 0.01. By reducing friction and wear, ORNL believes its coating could help improve energy efficiency and durability while also cutting the economic losses from friction each year, which is estimated to be worth around $1tn.
