Ceramic coating?

Ceramic coating? Anyone here ever ceramic coat the internals of their engine? I'm talking specifically the piston head, combustion chamber, (possibly valve faces as well?)
Coatings YES with BAD luck as the coating fell off the piston crown.
The piston "melted" UNDER the coating allowing "loose" pieces to destroy valves, rings, walls, turbines.
My method is to fit piston oil jet cooling AND Gallery Pistons.
I have had good luck when a PVD coating was placed on the valves.
I would ALSO coat the piston pins with PVD (black diamond) for this type of use.
There are many engines, European, the have coated combustion chamber/exhaust port PVD coating at EOM level.

Ah, so the ceramic ended up trapping the heat inside the piston. Interesting. I wonder what effect a full coating would have, vs just the face of the piston.
When you say PVD coating, do you mean something like this?

(Mods, I don't think a sponsor sells these, but in case they do, just using it as a reference!)

Piston Coating First, good information given about "techline" coatings, thanks.
Second, to Ceramic the piston ring-land/skirt would destroy the walls.
I too coat the piston crown with only VHT paint at times with unknown results and NEVER created a problem.
I WILL DUE THE RESEARCH for my Hydrogen fueled LS engine project.
I will try this coating you have recommended, thanks again.

When I had my headers coated by JetHot, I noticed that they also offered piston, bearing and other "coating" options for internals and was wondering if it was worth the expense of doing it. It sure looks like it's probably not worth it?
Coatings OK, the nature of "coatings", ALL could be classified in different terms.
MY 100% solution is PVD when required. (Physical Vapor Deposition)
We use coated Piston Pins, Ti-Valves, Ball Valves, Lifters, Rings, etc.
This type of PVD coating is referred to as "black diamond".
I have NEVER had a problem using this coating material.
Another type of PVD is Titanium Nitrate, great for steel top rings.
I have used this for Alcohol fueled engine use with 300% greater ring life.
