Cryogenics?

Post by Lunytune »

A guy was telling me about NASCAR doing cryogenics, very successfully. Key issue was possible increase in performance, but more important was to destress molecules in components so it would have better chance of finishing 2-3 hour race.

Ever heard of it being done in small engines?

Isn't cryogenics freezing living tissue cells for later use. I'm looking forward to that news article...

:D :D BTW - While back, Car & Driver printed pics of a 50's car put into a concrete time vault and recently opened, water leaked in, it was sad...

Cyrogenics (wiki)
The branches of physics and engineering that involve the study of very low temperatures, how to produce them, and how materials behave at those temperatures

Interesting topic for research

I've seen shops advertising cyrogenic treatment of parts such as cyls and pistons when looking for machine shops that would bore small cyls. Don't know much about it and benefits for a close to stock street scooter. But the technical side would be interesting in itself.

Almost cryo-treated my zip90 top end back in the day when I had it for an experiment, but chose to forego it..

Had found a place up in New Mexico or thereabouts that did it for $80 for up to 8lbs with a weeks turnaround time

Would be interesting to try again, supposed to have great benefits. Like a 5% gain on 100cc go cart engine they did

The way I understand it, its effects are similar to why camshaft shops let their bar stock sit outside for years to "age" it.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.

When I used to work as car mechanic and machinist way back when I was in my 20's, we used cyrogenic treatment on transmission components, mostly differential cases, ring and pinion gears. When you build cars that puts out 800-1200 horsepower with 1000-1500 foot pounds of torque in a split second, a lot of things tend to break.

I personally don't know anyone who cryo treated moped components though.

How is the process done?

Molecular stress sets up in casting of metal, and believe even in machining. The task is to "relax" the molecules, removing the stress. Best for temp, fatigue, wear, I don't now all benefits, I'm riding the learning surf.

Process as I understand is to freeze the item/s down to 300 below zero for 24 hours, let recover and then bake up to 300 degrees for a period of time. I'm still researching to learn more on this.

I have a connection of a guy with experience in it, and open to doing scooters if there can be a profit. I wonder how many in this forum would be interested in doing it.

I have no idea how it's done since we send all of our stuff to the mainland for this kind of stuff.

Lunytune is right about the basics of the procedure.The out come is to relive internal stresses ,it creates a finer grain crystal,that intern reduces the internal stress and I believe a "harder/tougher"steel. I know a couple common applications are expensive ($150) barber scissors and expensive rifle barrels($300-$500).Because of the finer grain the parts become "harder/tougher" thus less prone to wear.....Carp

Carp, one bit of history I read was Swiss watchmakers discovered hundred years or more the benefits of low grade cryo. They would pack watch parts in snow and let them set over the winter, and pack parts in caves through the winter. And we wonder why Timex could not compete with a true Swiss jeweled watch.

my friend's uncle is a doctor and he cryo treated some things, says he hasn't bought a new shaving razor in 7 years (it never gets dull because it is so hard). He also treated the heads of his golf clubs, It makes a big difference (I think he was claiming an additional 35 yards on his drive).

I don't know how much profit there is because cryo treatment has been around long enough, I think someone would have caught on by now...ceramic does the same thing for our purposes and is cheaper, it just takes more math because you are adding rather than treating the parts.

Try it first, research gains. Then shoot out some prices for us ;)

I would like to know in detail if possible the procedure of doing this. I work in a lab and have access to liquid nitrogen and autoclaves. It may be a possibility for me to try things :wink:

I know this is what the doctor used but I don't know the details...he did say he used gloves but I am sure you know that if you have ever dealt with liquid nitrogen(can be very fun stuff :twisted: ).
