Macroscale Superlubricity Achieved With Various Liquid Molecules: A Review [PDF]
Frontiers in Mechanical Engineering, 2019 Superlubricity is generally classified as solid superlubricity and liquid superlubricity according to the lubricants involved at the interfaces, and is a popular research topic in tribology, which is closely linked to energy dissipation.

Macroscale Superlubricity with a High Load‐Carrying Capacity Enabled by Nitrogen‐Doped Graphene Quantum Dots in Lubricated Silicon‐Doped Amorphous Carbon Films [PDF]
Small StructuresAchieving macroscale superlubricity with engineering materials is highly desirable for energy conservation, environmental benefits, and longevity of mechanical components. However, attaining superlubricity in aqueous‐lubricated systems with enhanced load‐

Macroscale Superlubricity and Polymorphism of Long-Chain n-Alcohols [PDF]
ACS Applied Materials & Interfaces, 2020 Simple n -alcohols, such as 1-dodecanol, show anomalous film-forming and friction behaviour under elastohydrodynamic lubrication (EHL) conditions, as found inside bearings and gears. Using tribometer, diamond anvil cell (DAC), and differential scanning calorimetry (DSC) experiments, we show ...

Macro-superlubricity in sputtered MoS2-based films by decreasing edge pinning effect
Friction, 2023 To date, MoS2 can only be achieved at microscale. Edge pinning effect caused by structure defects is the most obvious barrier to expand the size of structural superlubricity to macroscale.

Macroscale Superlubricity Enabled by Hydrated Alkali Metal Ions
Langmuir, 2018 Superlubricity based on hydration lubrication provides a near-frictionless lubrication state for the extreme reduction of friction in aqueous conditions. Nevertheless, how to obtain the hydration superlubricity under macroscale conditions with higher load-carrying capacity still remains a challenge and the mechanisms governing macroscale superlubricity

Friction, 2023 Macroscale rolling/sliding conditions are in the superlubricity, a little-studied topic so far. The purpose of this paper is to examine the formation of elastohydrodynamic lubrication (EHL) films by water-based lubricants (glycerol and polyethylene ...

LubricantsElectroless 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

LubricantsStructural superlubricity refers to the lubrication state in which the friction between two crystalline surfaces in incommensurate contact is nearly zero; this has become an important branch in recent tribological research. Two-dimensional (2D) materials

Achieving superlubricity with 2D transition metal carbides (MXenes) and MXene/graphene coatings [PDF]
Materials Today Advances, 2021 Two-dimensional (2D) materials have demonstrated unique friction and antiwear properties unmatched by their bulk (3D) counterparts. A relatively new, large and quickly growing family of two-dimensional early transition metal carbides and nitrides (MXenes)

Macroscale Superlubricity Achieved on the Hydrophobic Graphene Coating with Glycerol
ACS Applied Materials & Interfaces, 2020 Abstract Introduction of graphene-family nanoflakes in liquid results in a reduction in friction and enhanced wear resistance. However, the high demand for dispersity and stability of the nanoflakes in liquid largely restricted the choice of graphene-family nanoflakes thus far.
