Dont get me wrong, I am a huge fan of coatings. I have in fact used the techline coatings CBC2 and cermalube to good effect in the past. However I was talking to a friend mine recently about ceramic coatings as he worked on them in the electronics industry. He said that Aluminium oxide is the most common ceramic with excellent insulating properties (CBC2 is mostly aluminium power). Based on his experience he thinks that a more effective way to put a ceramic coating on a piston is to use an anodizing process. By using different voltages it is possible to control the surface finish of the ceramic and control the thickness of the anodized layer. The hardness of the layer could be further enhanced by heat treating the piston after anodizing. It could even be made a nice color. Since it is not sprayed or otherwise applied to the piston there is also no risk of it chipping off.
Just some thoughts
