University of Pennsylvania Engineers Reveal What Makes Diamonds Slippery at the Nanoscale

PHILADELPHIA –- They call diamonds “ice,” and not just because they sparkle. Engineers and physicists have long studied diamond because even though the material is as hard as an ice ball to the head, diamond slips and slides with remarkably low friction, making it an ideal material or coating for seals, high performance tools and high-tech moving parts.
