Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a coating composed of carbon nanotubes that imparts superlubricity to sliding parts. It reduces the friction of steel rubbing on steel at least a hundredfold. A paper on the coating is published in the journal Materials Today Nano. Superlubricity is the property of showing virtually no resistance to sliding; its hallmark is a coefficient of friction less than 0.01.
