What does that even mean? Alright, you caught my attention, What is a "cool combustion chamber" and Why on earth would it be the root cause of a coating failure?????

It's been a few years + since I contacted them, consider calling Swain and discuss with their personnel your desires and questions:

Oh, ok, I suspect there was a communication issue then. We've been Ceramic Coating for over 10 years, using the same materials as Swain and I have never seen or heard anything like that.

Outside of exceeding 2000F+ which would obviously cause bigger problems for you and your engine, , any flaking or peeling of your coatings would be the result of some processing error.

Knock on wood, we have never seen this conditions or experienced it in an internal engine coating scenario.

Investigation of Thermal Barrier Coatings on IC Engines

without going into a two year study of thermodynamics here on the forum i will just refer you to this engineering article. it is quite lengthy and talks about thicknesses and alot of science but essentially think about the properties of the components, the aluminum has it own thermal expansion properties, the head another, the coating another. the ceramic is a heat sink holding energy, the oil is splashing upon the bottom of the piston so the top and bottom surfaces have different temps, with low temperatures in the combustion chamber the coating does not absorb enough energy to function properly, hence it advantage being mainly on very high performance racing engines not street. enough cycles of expansion and contraction in a way that the coating cannot maintain its adhesion to the substrate, IE aluminum in this case, it will fail
