Does anyone know the process used by Racing Beat to harden their stationary gears? Is there more to it than just cryo-treating them?

I'm wanting to harden the stationary gears and e-shaft on my S5 N/A.

 

I am not sure, but you could have them coated with titainium nitride, that would make them very hard and smooth.

 

call and ask them, they have a line for general tech support.

 

Yeah, but they probably wont tell you! They dont like giving out info they worked to figure out?

 

just get some atomantium from wolverine, good ****!

 

Adamantium?

 

give me a break with the comic reference

 

Find a local industrial gear manufacturer.

They're probably case carburized, but there are a few different methods.

 

Care to list those other methods?

 

what is the ping method that i've heard people talk about?

 

I believe that you are thinking of shot peening, I know that it is a stress relief that they use on rods to make them stronger.

 

Thats the word yeah!

So how does it work? Could you do something like that on any rotary parts to make them more dense / stronger?

 

You can shot peen the root of each gear tooth, but the metal shot would of course damage any bearing surfaces so they would have to be re-ground. This is also done on industrial gears.

Other hardening methods include induction hardening, flame hardening, yadda, yadda, yadda.

There's a whole industry and science to hardening and heat treating methods. Lots of stuff to learn out there.

 

It's like sandblasting something with little metal *****. It's typically done to crankshafts and rods on reciprocating engines

Usually the cranks bearing journals are repolished and hard chromed after shot-peening.

I suppose you could do it to the e-shaft.

But I'm more intrested in j200pruf's idea, titanium nitride coating. Does anybody know if this has been done? If there aren't any serious drawbacks I think that would be the bomb

 

In RB's catalog it says Mazda did that to some of the RX's internals.

I've decided I'm just going to Cryo-Treat my engine's internals.

 

I have shot peened apex seals
