The explanation behind this makes sense. Make a surface smooth it creates less friction. I'm sceptical that it's all this article makes it out to be. Anybody had personal experience with titanium nitride coatings? Would guess this would be similar. Has anyone heard of the coating mentioned before?

And the crank/little end lubrication?....

Here's another one. Sounds like they're coating all bearing surfaces; wrist pin, connecting rod sleeves, needle bearing, cylinder walls, and even the rings. This article says they're smoothing the surfaces down before they finish them. Which is confusing for the rings/cylinder walls. Seems like the coating would break off the rings once flexed to fit in the bore. Also additional machining must be required so that a break in period to seat the rings isn't required (no cross hatch)?

I use a similar product on my Gun bolts: MicroSlick.

P-Series
Dry Film Lubricant
provides a low-friction surface for metal-on-
metal contact. The
P-Series
Coatings
are
formulated to withstand extreme temperatures
(~1200
°
F)
. This makes the coating ideal for
pistons and other wear components in high-
temperature systems, and
P-Series
coatings
maintain excellent adhesion even after
repeated thermal cycling.
These coatings
provide superior protection against high wear
,
galling and corrosion.

I dont believe in this stuff, i once used ceramic coated pistons in an engine, doesnt do as parts all wear un even and the constant expansion and contractions separate the coatings/films, eventhough they say it doesnt. Better off just using synthetic oil, imo.

We just need a Guinea Pig. I expect it is meant for race motors the will be torn down often.

. I expect it is meant for race motors the will be torn down often.

. I agree totally, they wear off fast, but also allow the engine to spin at 20,000rpm as the friction is so low.
