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

Friction of two-dimensional colloidal particles with magnetic dipole and Lennard–Jones interactions: A numerical study

Friction, 2019
We use Langevin simulations to study the sliding friction of two-dimensional colloidal particles on a substrate with randomly distributed point-like pinning centers.

Prospects and Challenges for Achieving Superlubricity in Porous Framework Materials (MOFs/POFs): A Review

Lubricants
Metal–organic frameworks (MOFs) and porous organic frameworks (POFs) have been extensively explored in recent years as lubricant additives for various systems due to their structural designability, pore storage capacity, and tunable surface chemistry ...

Origin of superlubricity of diamond-like carbon (DLC)

Friction
Hydrogenated diamond-like carbon (H-DLC) is typically produced as a coating or thin film through plasma-enhanced chemical vapor deposition (PE-CVD). H-DLC is relatively hard and well known to exhibit superlubricity.

Whole course oil-based superlubricity for polyetheretherketone-bearing steel sliding pair by introducing tribocatalytically active dialkyl-dithiophosphoric-modified copper nanoparticles in poly-alpha olefin oil

Friction
At present, achieving oil-based superlubricity depends on lubricating oil viscosity and rubbing pair materials excessively. Therefore, establishing a new route is of scientific significance and application value.

Superlubric sliding ferroelectricity

Applied Physics Reviews
Structural superlubricity at incommensurate van der Waals interfaces leads to ultra-low friction coefficients. In this study, we try to apply a similar strategy to reduce the barrier of sliding ferroelectricity in van der Waals bilayers/multilayers with commensurate interfaces, since the writing speed in ferroelectric memories would be enhanced almost ...
