An effective and simple method is reported to enhance the property and economics of graphene lubricants, that is, 3D porous graphene and T161 are proposed as hybrid lubricant additives. Compared with PAO 6, 3D PG-T161 can reduce the friction coefficient of 316 ASS (Austenitic stainless steel) by about 4.0%, 26.1% and 73.1% respectively under the normal load of 5 N, 50 N and 100 N, and the wear rate is reduced by about 28.9%, 65.6% and 97.8% respectively. The excellent tribological performance is attributed to the formation of uniform protective lubricating film. These findings are of great significance for enhancing the tribological properties of ASS and expanding its application range.
