Impure Chemicals Turn Carbon Surfaces Superslippery
Researchers from Osaka Metropolitan University and Fraunhofer IWM have discovered that chemical impurities can actually improve the sliding performance of carbon surfaces. This phenomenon, known as shear-induced aromatization, could lead to the development of self-repairing, low-friction coatings.
Why it matters
Understanding how to achieve superlubricity could significantly reduce energy waste and mechanical wear in industrial machinery.
Engineers often treat impurities as a problem to eliminate in order to improve material performance. But new research from Osaka Metropolitan University and Fraunhofer Institute for Mechanics of Materials IWM suggests that in some cases, a little chemical messiness is exactly what helps materials slide more smoothly.
