What if there was a VERY easy way to ceramic coat the diff's wearing and bearing surfaces and the ceramic coat was 80X slipperier than steel-oil-steel and 85% the hardness of diamond..??

Sounds too good to be true right?

Snooping around Argonne National Labs' web site will do 2 things:

Allow you to do exactly that.
Make it so you actually believe the claim..!

I have:

Restored, smokey, worn old engines to health, with a noticeable improvement in fuel economy or power, depending on how heavy your foot is. (Ceramic Layer is 0.5 micron thick. Thats a total of -2 microns of play in a bearing or piston/cylinder)
'Buggered up' a gearbox as the syncros (that rely on friction) stopped working to the point that required the 'gear changing without a clutch' trick.
Restored whiney old diffs. (non Limited slip! Unless you want to unlimit it!)
