摘要:
Nanoparticle compositions contain a graphene-based material. A preparation process involves providing several components and milling a mixture. The nanoparticle compositions can be used as a lubricant additive to improve tribological performance, in particular to improve anti-friction and anti-wear performance on metal parts. A corresponding lubricant composition contains these nanoparticle compositions.
