I know it sounds crazy, but I've seen this stuff work.

There is now a push to get these "coatings" in all gear boxes and drive assemblies at the nuke plant where I work because oil analysis has proven that the amount of metal wear is significantly reduced.

Efficiency is up, heat is not an issue and longevity is 5 time longer than previous maintenance history.

I was thinking about having my ring and pinion coated and going to a lighter weight rear diff oil. I am also considering having all the brake guide pins done ...

There's also proof that cryo treating highly stressed parts like gears etc., also increases durability.

I have never seen any proof that cryo treatment does anything.

It is easy to do cyro treatment and it doesn't hurt anything if done properly. But all of the so called "proof" I have seen is only claims. Nothing scientific, no explanation of the mechanism at work.

Some alloy steels have phases that do not form at room temp only at cryo temps. They are stable after they form, kershaw knifes are quenched in Liquid nitrogen for that reason, Austenite phases.

This can be done if you control the alloy for this purpose.

But just dipping whatever part you have around is very unlikely to help anything.

This is also a rip off scam that is done with drill bits in industry.

Coatings could work, but cyro should be that last thing you should spend your money on.
