Cryo-Rem Racing components

So I'm having this process don that to my spare transaxle for the racecar. Its a finishing process that gives the moving parts in the tranaxle a mirror like chrome finish. Apparantly it gives you a dramatic reduction in friction, eliminated metal to metal pitting,reduces Lubrication Temp,extends part life!

Anyone out their who have tried this process?

The process is called Isotropic Normalizing, and while not as magical as claimed by some, is probably a good idea for R&P and gear teeth. Problems arise, though, when the parts are not properly masked, and EVERYTHING comes back with a mirror finish. You only want the working surfaces to be polished.

Huh - sounds like it makes all the grains point the same direction...

[Geary]

No, it's a polishing process in which the parts are vibrated for hours in a polishing medium, taking off all tiny high spots, while a chemical bath somehow fills in the microscopic low spots. It's real, unlike some other hocus pocus treatments.

"Grains pointing in the same direction" is when the material is formed (at high heat) into the general shape of the finished product through the forging process.

[Randy Webb]

Right. But where is the isotropy?

Anyway, good to know we have a new surface treatement available.

Oh, BTW, the reason not to polish many other surfaces is that the polished surface will not retain oil very well.

Polishing the backside of the ring gear makes it slippery, which could allow it work back and forth on the diff. Polishing the mainshaft makes the parts slide on & off TOO easily, as the dimensions have been reduced slightly
