Nickel Plating piston tops etc: more timing advance

In a perfect world we'd have a 100% insulating surface with zero thermal mass on all the surfaces in a combustion chamber.

Hmmm... good point.
However:
The quench distance when burning hydrogen is 0.5mm vs 2-2.5 mm for petrol/diesel.

ie: If the surfaces are producing a tiny amount of hydrogen the boundary layer becomes more hydrogen rich the closer you get to the surface.
So now;
your quench distance decreases; producing more surface heat and thus more hydrogen in a positive feedback loop.

IMHO 'the proof's in the eating' as can be evidenced from my earlier link where this idea WORKED! And worked well..!!!
You did read the study..?

Certainly well enough to make coating said surfaces (cheap/easy) worthwhile.

As to how you'd get it to adhere to combustion chamber, I have no clue.

A quick look points to it being a solid lbricant and possibly soluble in hydrocarbons.
A quick search points to it being a good solid lubricant:

And possibly soluble in fuel..?

ie: A possible fuel additive..?
