Seen something from a new company in Columbus oh that is developing this technology. They claim several benefits from it. Anybody have any knowledge about it?

No more than you do. I'm keeping an eye out.

Isn't ceramic extremely brittle. One little detonation stroke and BBBOOOOOMM

That's what I thought. Supposedly not an issue with these. They claim better resistance to detonation.

Here was an on-road demonstration they did:

They claim that the pistons are lighter than their aluminum counterparts and also offer a hp increase. Interesting technology and if it's legit I'd like to try them in a quick revving 5.7 application.
They're not on the market yet. Still doing market research according to what I've read on their Facebook site. It would be sweet if I could beta test a set...

Resistance to detonation and no detonation are not the same thing. I really don't see this going anywhere. I can promise you, if there was some merit to it, the big manufacturers would be there already.

Now watch GM make a public announcement tomorrow about the switch to ceramic pistons. lol

Honda used them in F1 many years ago. No rings, big oil tank...

Interesting. I wonder how their efforts compare to current efforts by the company mentioned above. I would think there have been advancements in the materials and technology to manufacture them. I'd love to know what problems made them decide to go back to aluminum Pistons.
I wonder if the company attempting to make them were aware of such things and have addressed them. I wish they were a member here and would add input.

I would imagine that the most current engine parts materials would be found in Formula One. Those teams have unlimited funding and over the years technology trickles down into the production cars. Problem...........you'd have a better chance of walking up to the president of the United States, back hand bitch slapping him across the face and the secret service not doing anything about it than getting to see the most current technology in Formula One.

there are some very ductile ceramics, but machining cost is crazy high. you can green machine it with normal HSS but once fired you need diamond amalgam tooling to cut it. and even then it's a long, slow cut.

Teams are still beholden to strict rules. Some of those rules dont allow for off the wall materials. For example.. there were teams experimenting with alloys that included fairly highly radioactive metals for pistons, rings, etc. FIA said **** that, no.

we now use CMC's in the hot section of our LEAP engines...

a little vid for you guys... i'll let ya know if they Let me make pistons with them LOL!!!

When I was working F22 development, I had a Pratt engineer tell me about their experience with ceramic blades. Everything went great until the first start after a wet start. With fuel soaked blades, that didn't go to well. Would be interesting to see how GE has solved that, I'm sure you can't post that on the forum...

Fuel soaked reciprocating engines would seem to have the same issue.

Are ALL ceramics as what would be used here absorbent? Then I see the issue....
