Title: Approaches for Achieving Superlubricity in Two-Dimensional Materials

Abstract

Controlling friction and reducing wear of moving mechanical systems is important in many applications, from nanoscale electromechanical systems to large-scale car engines and wind turbines. Accordingly, multiple efforts are dedicated to design materials and surfaces for efficient friction and wear manipulation. Recent advances in two-dimensional (2D) materials, such as graphene, hexagonal boron nitride, molybdenum disulfide, and other 2D materials opened an era for conformal, atomically thin solid lubricants. However, the process of effectively incorporating 2D films requires a fundamental understanding of the atomistic origins of friction. In this review, we outline basic mechanisms for frictional energy dissipation during sliding of two surfaces against each other, and the procedures for manipulating friction and wear by introducing 2D materials at the tribological interface. Lastly, we highlight recent progress in implementing 2D materials for friction reduction to near-zero values-superlubricity-across scales from nano- up to macroscale contacts.

Large-scale Manufacturing of Nanoparticulate-based Lubrication Additives for Improved Energy Efficiency and Reduced Emissions

Technical Report Erdemir, Ali

This project was funded under the Department of Energy (DOE) Lab Call on Nanomanufacturing for Energy Efficiency and was directed toward the development of novel boron-based nanocolloidal lubrication additives for improving the friction and wear performance of machine components in a wide range of industrial and transportation applications. Argonne's research team concentrated on the scientific and technical aspects of the project, using a range of state-of-the art analytical and tribological test facilities. Argonne has extensive past experience and expertise in working with boron-based solid and liquid lubrication additives, and has intellectual property ownership of several.

Operando tribochemical formation of onion-like-carbon leads to macroscale superlubricity

Journal Article Berman, Diana ; Narayanan, Badri ; Cherukara, Mathew J. ; ... - Nature Communications

High contact pressure and shear during relative movement of the sliding interfaces are known to cause structural or chemical modification or complete phase transformation due to the stress induced chemical reaction. Such reactions can manifest either formation of tribofilm or induce enhanced wear at the tribological interface. The nature of these stress-induced reactions at the atomistic level and formation of byproducts at the tribological interface, however, remain poorly understood and pose uncertainties in predicting the tribological performance of the tribosystem. In this paper we demonstrate that, when pristine molybdenum disulfide layers in their two dimensional form are coupled with nanodiamonds,more »« less

Molecular tribology of hydrocarbon systems

Conference Harrison, J.A.

The development of new technological applications involving diamond coatings has accompanied recent advances in the chemical vapor deposition of diamond coatings. Since a great number of applications involving these films, which pre-dominately show (111) and (100) facets, deal with the motion of diamond on diamond, understanding the tribological properties of these diamond facets is paramount. If the atomic-scale mechanisms which give rise to the observed tribological characteristics were understood, this knowledge might ultimately lead to the design of coatings with specific friction and wear properties. With this in mind, we have been using molecular dynamics to examine the atomic-scale phenomenamore »« less
Superlubricity and wearless sliding in diamondlike carbon films.

Conference Erdemir, A

Diamondlike carbon (DLC) films have attracted great interest in recent years mainly because of their unusual optical, electrical, mechanical, and tribological properties. Such properties are currently being exploited for a wide range of engineering applications including magnetic hard disks, gears, sliding and roller bearings, scratch resistant glasses, biomedical implants, etc. Systematic studies on carbon-based materials in our laboratory have led to the development of a new class of amorphous DLC films that provide extremely low friction and wear coefficients of 0.001 to 0.005 and 10{sup -11} to 10{sup -10} mm{sup 3} /N.m, respectively, when tested in inert-gas or high-vacuum environments.more »« less

Graphene - MoS ₂ ensembles to reduce friction and wear in DLC-Steel contacts

Journal Article Mutyala, Kalyan C. ; Wu, Yimin A. ; Erdemir, Ali ; ... - Carbon

Recent demonstration of two dimensional (2D) solid lubricant materials to minimize friction to unmeasurable levels (superlubricity) and reduce wear at macroscale propelled further research investigations in the direction of exploring their potential in industrially relevant material combinations such as steel and diamond-like-carbon (DLC) in sliding contact. In this study, we have used a combination of 2D materials i. e. Graphene and MoS ₂ as a solid lubricant to reduce friction and wear in steel-hydrogenated DLC contacts even at high contact pressures and sliding speed. Sliding friction tests conducted under dry nitrogen conditions shows a reduction of friction and wear bymore »« less
