ceramic coating

[isprins]

I think that it should be possible to apply a ceramic coating to a pulsejet engine, ceramic coatings are used on jet turbines, and on piston crowns.

I have been thinking of ceramic coatings also. We just instaled a new chimney in our shop, it was the more expensive brand and where it goes up through the ceiling/roof it was "triple wall". Meaning it had a layer of metal, ceramic coating, metal, air gap, metal. This stuff is gueranteed to last at least 6 chimney fires up to like 2,000 degrees. And that doesnt even mean failure, just warrenty. I think if you could do something similar you could have an extremely long lasting pj.

Yet again, this would have to be one of the best running pulse jets to go to all that work and money. What do you guys think?
