Paul,

There is a technology that would be better than Teflon, "Near Frictionless
Carbon" that has a coefficient of friction of ~0.004 as opposed to Teflon's
0.04.  I have enclosed a PDF of a writeup on it, I know that two companies
have licensed the technology, but I don't know their status on making parts,
whether they want large manufacturing base for parts, or can make evaluation
samples. The contacts for the companies are shown below.

Thanks Bill.
That is REALLY interesting. One tenth of Teflon!!!
The pdf was 1998. I wonder why we have not heard more
about it. DLC is widely used in Formula 1 and other race
engines. In fact it is used in the Mazda RX8 engine.

I'll copy them this email.

Here is another site on the subject.

Another pdf as of 2006. I am looking for temperature
properties.

Million-cycle reciprocating wear tests have been carried out to
determine the ultimate wear lifetime of near-frictionless carbon
(NFC) coatings applied to production fuel-injector tips. Wear
tests were performed in existing and reformulated gasolines as
part of a study to improve fuel systems for spark-ignited,
direct-injected (SIDI) engines. Ball-on-three-disc (BOTD)
tests were performed to determine the lubricity of the
gasolines, and the wear surfaces were analyzed using Raman
spectroscopy. NFC coatings reduced friction and total wear
by up to 48% and 39%, respectively. No evidence was seen
of coating graphitization, the formation of transfer films
from the coatings, or the presence of chemical protective
films originating from the gasolines.
