Ceramic Coated Apex Seals?
 

I know somewhere, someone mentioned this before. But never in enough detail. Someone said that if you coat the apex seals with cermamic, it will flake off. Is it possible to coat it a few times, or use a really strong coating like the coating used on the 787B? The reason I ask is because, what if you use really strong seals (which would normally wear the crap out of your housing) and coat them, and even you housing with cermit coating? Would this possibly solve a bit of the

what's that,,,,,PING.......BOOM,, your engines dead.....delema?

and the ceramic coating should solve the wear problem to? just wondring?

ceramics are brittle (ever dropped a coffee mug) the durability of an apex seal comes from its size (2mm or 3mm) and the special alloys they are made of which im geussing are as minimally brittle as possible (in addition to other properties) so that the seal can survive the impact of a strong ping. i doubt ceramic coating would allow a seal to survive harder or more frequent pings, but might lead to less friction wear on the housings.

Ceramic Coating
 

That's kinda what I was saying in the post above. I know that the really strong alloys (RA seals, for example, or maybe even something stronger) are more resistant to "knock" but they are not freindly on the rotor housings. The ceramic coating should fix that problem.

they're not coated, they are made of ceramic

Ceramic Coated Apex Seals
 

I know the apex seals are ceramic, and not coated,,, in a sense, there are 3 materials that I know of that apex seals are made of,, each with there own advantage, there are Carbon, Ceramic, and Steel. What I was thinking about was a Steel Apex Seal coated with ceramic,, that way it would have the strength of steel and the friction charicteristics of ceramic

Steel alloy(s) = 99% of all apex seals
Carbon = used in some racing engines. They work good, break in quick and die quick. 5000 miles might be the life expectancy of a carbon seal. Big advantage if you rebuild offen and do not have time to break in the motor prior to dyno tuning.
Ceramic = insanely expensive. Not used by enough ordinary people to develop good feedback. $3000 for a set?

Carbon apex seals last alot more then 5000 miles mabye if you are at 10,000 rpm for 5000 miles there is a guy up here with 178,000 km on his

Apex Seals
 

Well, I heard that NRS has ceramic apex seals for under a grand. But I guess the only way to find out if Ceramic Coated Apex seals made from a strong material. (titanium maybe...lol,, hey its really strong,, and really light.) will work is to go out and do it,,anyone got a spare 12a/13b on them....lol.

ceramic coating will come off with friction....
