Just wondering if anyones treated any of there internals to Titanium nitrate process?? Ive seen and heard about it a few times on TV, and Race cars have this process done to them. i was wondering if this is somthing a regular joe shmoe could afford, and would it be worth it on Rotarys?

here are the advantages from Titanium nitrate process:

-Excellent Corrosion Resistance
-Superior Erosion Resistance
-High Heat Transfer Efficiency
-Superior Strength-to-Weight Ratios

how much does it cost, i tmight be worth it just to buy another rebuild set. as far as Corrosion, i dont think this is really a problem for rotaries hehe

Im not really talking about the corrosion aspect of this, but more of what it does to the metal itself. This process makes all metal types stronger. Like i said they use them on race cars (rods, pistions, cams etc.) that ive seen on TV (CutChopRebuild show has done this <--speedvision ) because the metals are much tougher, can take alot more abuse, wear & tear.

I guess my main question is has anyone done this to a rotary? Or heard about it?

What part would you want to use this on?

You dont want heat transfer on the rotor itself.

sounds similar to the ceramic coatings that can be done to the rotor faces and gears. there was an old write up somewhere. anyways, heres swain technologies . Its under miscellaneous. TBC (thermal barrier coating) is the ceramic coating. PPC (peko poly-moly) is the coating that helps reduce friction and there fore reduces heat. TBC like you said helps with the transfer of heat. this stuff has been around for a while now so i guess there's nothing bad about it. the cost isnt too bad either. the only bad thing is that (of course) the engine internals have to be taken out. but if i was doing a rebuild i would definitely have it done.

What would you have it done on?

the rotor faces and the consentric ring.

Ti. Nitrating is more of a wear surface application. It is a very hard and strong surface but the problem most people have is that it leaves a green color which they think is wrong and have it ground off.

No reason to treat the rotor faces, and the side plates are already nitrated from the factory. Not sure what you are referring to as the "concentric ring", but if you mean the thrust surface on the rotors, I don't believe I'ev ever heard of massive wear on that area.

maybe the apex seals.....or would that make them wear down the housings too fast?

Tofuball

I'm with Aaron on this. I cant really see a use for it, especially on the rotor face, it is not a wear surface, and you want it to transfer as LITTLE heat as possable.

andrew lohaus

possible the rotor housings......help the chrome out a little?

Biggest places to use Ti. Nitride, on the rotor bearings and eshaft, stat gears, and rotor gears, gears in the transmission, Ring and Pinion, the list coudl go on some more.
Hey Aaron, what about side seasl? that means both the housing and seal woudl be Ti. Nit. Theat seems to work really good in the piston racing world (having both contact surfaces in contact with each other).

i was thinking more along the lines of what J200pruf mentioned... (rotor bearings, eshaft, stat gears, and rotor gears)... But i dont know too much about this so im only assuming it might help if say your motor blew, maybe there wouldnt be as much damage done? But then that could work vs versa. If everything is strong then somthing has to let go. I guess im just talking out of my *** at this point since this is somthing new to me and im trying to learn more about it and if it would be worth doing.

isnt cryogenic easier, more beneficial and more than likely cheaper?

Side plates are nitrited iron, not titanium nitrite, big difference.

also you do NOT want this, or anything else hard on bearings they are coated with indium lead for a reason,..

e-shaft- maybe, but since these seldom wear out anyhow it would be kinda pointless, and it doesnt actually contact the bearings so it wouldnt reduce friction really.

Rotor housing- Bad idea, unless you can come up with a way to reproduce the micro pores/channles in the stock chrome in the right amouts( to many channles = scrated housings, to many pores = chatter marks)

only place i can see is the rotor seal grooves ( i think these are crome plated on later motors though, but it might be better) and the oil seal inner diameter/lip (chrome plated from the factory, but titanium nitrite might be better once again.

-forgot to add, that the rotor gears/ stat gears, though ion nitited from the factory after 89, might benifit from this and it would certainly help s4's-

on the Le Mans rac car that did the 24hour race it had treatment done to it parts with a process i can't recall.

It was in the technical write up on the car.
So i think we should all read the write up and see what they did and do it to our cars...

Their objectives are the same as ours in the write up

if you do the rotor gear is prolly coming out. it scuffs that and the irons, in the beginning statges
