i use to work in a machine shop and they had magazines laying around. so while i was looking through one i came across an article about a company that came up with a way to stop the heads from warping in military diesel engines. they did some testing and found that the exhaust valves get alot hotter than the rest of the head and cause warping. the company came up with a coating to put on the head to resist temps. i wish i still had the article but here is the companies name anyone ever hear of them. http://www.adiabatics.com/

 

Most of the warping on the CTDs is from the manifolds expanding and contracting isn't it? I imagine the ceramic coating could help that a little but a ceramic coated (or even not) ATS would be even better.

 

i found the article take a look http://www.machinedesign.com/ASP/vie...MDSite&catId=0

 

I wasn't aware there are coatings that can withstand that type of atmosphere, even if there were I'd be quite reluctant to put it on the head gasket sealing surface just in case. The route problem for them is most likely the 200ksi stress, I highly doubt if they brought the temperature down that it'd help the material all that much. Looks like their solution is adding more material and just letting it yield locally. It is interesting reading none the less, I'm doing finite element models right now at college, and I'm literally doing the temperature & engine analysis right now (hogs cpu so I have to find something else to do while waiting between simulations ) but it is a whole motor, not just one part.
