In rotary engines, Curtiss Wright found that a thin TBC was able to raise the
rotor surface temperature enough to reduce hydrocarbon emissions but no other
real benefits were noted. Other researchers (Moller, for one -- Jeff know
anything about this?) have had mixed results. Basically, the challenge is to
keep the stuff on the rotor because if it comes off the engine will fail. So
I guess the risks have been shown to outweigh the benefits.
