{{site specific term}}
It may be possible to passivate some base materials by tacking on graphene sheets onto the surface. 
The bonds found in [[sandwich compound]] may be usable here. 
Especially for materials that are otherwise hard to passivate this may be a possible option.

[[Graphene sheet lining]] may be an option for bigger sized gears 
where teeth are no longer single atoms but teeth instead already approximate evolvent or cycloid profiles. 
See: [[Crystolecule examples#Gears with bigger teeth made from multiple atoms]]

== Feasibility ==

At this point this is just a wild idea, it may or may not work. Or something in-between. 
More detailed investigations will be necessary to tell.

The possible concerns are numerous and include at least:
* Can the tack on density by high enough such that between the tack ons thee is not too low of a stiffness?
* Will a too dense tack on pattern distort the graphenes electronic structure so much that it will become too reactive or even fully unstable?
* How well does the graphene conform to the underlying material?
* How much curvature is ok before localized kinks or too much change in electronic structure?
* How well can the graphene smooth out steps below in the underlying material?
* ... and so on and so forth ...

== Choice of terminology ==

Here the "lining" part in the sense of pillow lining cushion lining ore rather more in the sense of
[https://en.wikipedia.org/wiki/Brake_lining brake lining] a thin strongly connected layer to a stiff and hard background material
just that here
* its meant to lower friction rather than increase it
* it's not a consumable bur [[wear free]]
