Covalently Bonded Heterostructures with Mixed-Dimensional Carbons for Suppressing Mechanochemical Wear of Diamond under Heavy Loads
Bo Yan,

et al.
Abstract:Diamond is widely acknowledged as the hardest naturally
occurring
material. Nevertheless, when exposed to friction against ferrous metals,
it is prone to graphitization or amorphization, which limits the utilization
of its extremely high hardness and wear resistance. These issues have
persisted for decades without an effective solution. Here, we report
that a covalently bonded heterostructure with mixed-dimensional carbons
as a high-performance solid lubricant could effectively reduce diamond
surface friction … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
