Study on the Superlubricity Behavior of Ions under External Electric Fields at Steel Interfaces

, 2023
Realizing macroscopic superlubricity in the presence of external electric fields (EEFs) at the steel interfaces is still challenging. In this work, macroscopic superlubricity with a coefficient of friction value of approximately 0.008 was realized under ...

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 ...

Superlubricity of Black Phosphorus as Lubricant Additive

, 2018
Superlubricity is defined as a sliding regime in which friction, or the resistance to sliding of two relatively moving surfaces, almost vanishes. From a practical point of view, the development and use of new materials that can enable superlubricity ...

Superlubricity of dry nanocontacts

, 2008
We discuss how various forms of dry superlubricity, recently observed on the nanoscale, have been interpreted by simple phenomenological models. In particular, we review the cases of static and dynamic single- contact lubricity, thermolubricity, and ...

Investigation of the mechanisms for stable superlubricity of poly(vinylphosphonic acid) (PVPA) coatings affected by lubricant

Friction, 2016
The stability of the tribological properties of polymer coatings is vital to ensure their long term use. The superlubricity of the poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V/polytetrafluoroethylene (PTFE) interface can be obtained when lubricated

Evolution of tribo-induced interfacial nanostructures governing superlubricity in a-C:H and a-C:H:Si films

, 2017
Hydrogenated amorphous carbon (a-C:H) is capable of providing a near-frictionless lubrication state when rubbed in dry sliding contacts. Nevertheless, the mechanisms governing superlubricity in a-C:H are still not well comprehended, mainly due to the ...

Macroscale Superlubricity in Water-Based Systems on Electroless Ni–P Coatings via P-Content Optimization and Tribofilm Control

Lubricants
Electroless Ni–P coatings are widely used for corrosion and wear protection, yet their ability to deliver water-based superlubricity and the role of phosphorus content remain insufficiently understood. Here, electroless Ni–P coatings with four P contents
