▎ 摘  要

Recently, most of the researchers focused on investigating the superlubricity of glycerol or glycerin/water solutions, yet all of them have no attempt to follow with performance about their lubricity under high load and fast rotational speed. In this article, the lubricity of glycerol was systematically investigated under 98 N and 1,450 rpm using a four-ball wear machine. Interestingly, results showed that friction-induced graphene layers were first discovered during sliding, meanwhile, friction-induced graphene layers were closely related to the high flush temperature rise and catalysts. The synergy of graphene and glycerol elastohydrodynamic film on wear scar played an important role in obtaining low friction and wear-less.
