Humidity‐Resistant Ultralow Friction in Diamond‐Like Carbon Coatings Enabled by Graphitic Nanodiamonds

Small Structures, Volume 6, Issue 10, October 2025.
The functionalization with graphitic nanodiamonds enhances friction reduction in diamond‐like carbon‐based interfaces. It promotes the formation of a stable, highly graphitic transfer layer, maintaining the core–shell arrangement. This study extends recent advances in superlubricity, providing insights into lubrication mechanisms in humid environments ...

Functionalized graphene-oxide nanosheets with amino groups facilitate macroscale superlubricity

Friction, 2022
AbstractGraphene-oxide (GO) has been recognized as an excellent lubrication material owing to its two-dimensional structure and weak interlayer interactions. However, the functional groups of GO that can contribute to anti-friction, anti-wear, and superlubricity are yet to be elucidated.

Why is Superlubricity of Diamond‐Like Carbon Rare at Nanoscale?

Small, Volume 20, Issue 33, August 15, 2024.
Diamond‐like carbon coating (DLC) exhibits notably distinct frictional behavior across macro‐, micro‐, and nanoscale friction tests conducted in inert gas environments. This peculiar dependence of DLC friction on the sliding contact scale is attributed to the instability of transfer films within the small contact area at the nanoscale, which hinders ...

Macroscale superlubricity enabled by the synergy effect of oil and S–C co-infiltration coating on 20CrMnTi steel surface

Friction
To explore macroscopic superlubricity in industrial fields, S–C co-infiltration treatment refers to the sulfurization of carburized gear steel to achieve a synergistic lubrication effect. The carburized layer at the bottom provides high-strength support.
