Argonne Discovery Yields Self-Healing Diamond-Like Carbon

A group of tribologists – scientists who study the effect of friction in machines – and computational materials scientists at Argonne recently discovered a revolutionary diamond-like film that is generated by the heat and pressure of an automotive engine. The discovery of this ultra-durable, self-lubricating tribofilm – a film that forms between moving surfaces – was first reported yesterday in the journal Nature. It could have profound implications for the efficiency and durability of future engines and other moving metal parts that can be made to develop self-healing, diamond-like carbon tribofilms.
