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 ...

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

Atomic simulations of kinetic friction and its velocity dependence at Al/Al and alpha-Al_2O_3/alpha-Al_2O_3 interfaces [PDF]

, 2005
Kinetic friction during dry sliding along atomistic-scale Al(001)/Al(001) and alpha-Al2O3(0001)/alpha-Al2O3(0001) interfaces has been investigated using molecular dynamics (MD) with recently developed Reactive Force Fields (ReaxFF).

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 ...
