Macroscale Superlubricity with Ultralow Wear and Ultrashort Running-In Period (∼1 s) through Phytic Acid-Based Complex Green Liquid Lubricants.

ACS Applied Materials and Interfaces, 2023
Liquid superlubricity has attracted much attention, due to its ability to significantly reduce friction on the macroscale. However, the severe wear caused by the long running-in period is still one of the bottlenecks restricting the practical application

Macroscale liquid superlubricity achieved with mixtures of fructose and diols

Wear, 2021
Abstract Superlubricity has numerous benefits in industrial applications, but its practical applications are restrained from its heavy dependence on special atmosphere environment and the use of low-dimensional materials. This paper reports a novel and facile method to macroscale liquid superlubricity for steel tribopairs, which realizes superlow ...

Macroscale Superlubrication Achieved with Shear‐Thinning Semisolid Lubricants

Advanced Materials
AbstractMacrosuperlubric materials are pivotal for reducing friction and wear in engineering applications. However, current solid superlubricants require intricate fabrication and specific conditions (e.g., vacuum or inert atmospheres), while liquid superlubricants are prone to creep, leakage, and corrosion.

Friction. Macroscale superlubricity enabled by graphene nanoscroll formation.

Science (New York, N.Y.), 2015
Friction and wear remain as the primary modes of mechanical energy dissipation in moving mechanical assemblies; thus, it is desirable to minimize friction in a number of applications. We demonstrate that superlubricity can be realized at engineering scale when graphene is used in combination with nanodiamond particles and diamondlike carbon (DLC ...
