The tribological properties of poly(ether-ether-ketone) (PEEK) against steel was evaluated by a ring-on-flat type tribo-test under rotating motion. Addition of poly(tetrafluoroethlene) (PTFE) as solid lubricants improved the load-carrying capacity of

Diamond-like carbon (DLC) coatings continue to attract attention for their low friction and high wear resistance. The transferred or transformed layer, which has a high sp2 carbon content induced by cyclic friction, results in an ultralow friction co

A series of activated carbons was prepared using a two-step activation process. The starting glass-like carbon spheres were heated at 500℃ for 3 h (first step activation), and then at a low temperature, below 415℃, for different times (second ste
