You must be very bad at your job as a mathematician because you suck
as an engineer.

Diamond-like carbon, DLC harder than natural diamond.
"In short, diamond-like carbon (DLC) can coat things and make them
last forever.
DLC is harder than natural diamond and slicker than Teflon. That
combination gets more horsepower from engines, longer lifetimes from
mechanical parts that rotate and slide, survival of fragile optics in
hostile environments, and it saves lives by making better medical
options available."

that's cause we're not very good at making them. each individual
crystal structure itself is certainly pretty strong.

hey, that reminds me, whatever happened to ceramic coated pistons and
valves and those high efficiency adiabatic car engines we were
supposed to have by now? they in some secret government warehouse with
the nuclear car, the personal jetpack, and the ark of the covenant?

Well, some things have been released. Velcro, for example. The oil companies
are paying the government to keep the pistons and similar things a secret.

The sad part is that there are people who will read this and think I'm
serious.

I don't know about these "diamond like carbon" coatings, but actual
diamond films are used as coatings for wear resistance despite
diamond's brittleness:

Developments in diamond coatings allow tools to work harder, last
longer.

Some ceramics have made their way into auto engines, both in the
catalytic converters and the blades on turbosuperchargers.
I imagine the problem with using them on pistons and cylinders is
differential heat expansion compared to metal, causing the ceramic to
de-bond from the surface it is applied to.
