As to how you'd get it to adhere to combustion chamber, I have no clue. |
The problem is that at the boundry layer of the combustion gasses it is pretty much impossible to get that high of temps. That's why you end up with unburnt fuel. The coolness of the metal surface (200 - 300 °F is cool in terms of starting and maintaining combustion) quenches the flame front causing it to not reach the very edge.
In a perfect world we'd have a 100% insulating surface with zero thermal mass on all the surfaces in a combustion chamber.
