Superlubricity and tribochemistry of polyhydric alcohols

The anomalous low friction of diamondlike carbon coated surfaces lubricated by pure glycerol was observed at $80\text{ }\ifmmode^\circ\else\textdegree\fi{}\text{C}$. Steel surfaces were coated with an ultrahard 1 \textmu{}m thick hydrogen-free tetrahedral coordinated carbon (ta-C) layer produced by ... View More
