Cryogenic treatment of a coil winding.......-300 degrees

[gitterdug]

I became aware of the cryogenic treatment of gun barrels about 15 years ago. By treating a barrel of a gun with supercold tempering at -300 plus degrees, the molecular structure of metal is realigned and destressed. I am greatly simplifying the process, but in essence, that is what occurs. The molecules line up end to end. It is a permanent treatment and is now used for many different metals.

How does this relate to metal detecting? Ever since I became aware of it, I have wondered if the treatment of the coil windings would benefit from such a treatment. To my non-scientific, but gut fueled thinking.....realigned molecules within the wiring itself would assist in the flow of electrons from the machine, and perhaps increase the size of the field developed by the coil. I am going to post this to several forums here for input.

I went to the website here: http://www.300below.com/ , and asked them that question. I thought it would be a subject perhaps for consideration here as well. I know there are some engineers on here, and this might be a short lived topic, but on the other hand, in my now 38 years detecting, I have never seen the subject raised. So, ok, tell me why or why not realigning the molecular structure of the wiring would or wouldn't enhance the size of the magnetic field, of speed of the signal.

IF I am totally off my rocker, just tell me, and we can move on.

Dennis, with a BRRRRRRRRRight idea!

I think it could be aN IDEA to be pondered,please keep me posted

Yes, get an old non working coil and see if it can be revived..........NGE

A coil assembly is made of different materials which would contract at such different rates it would come apart or shatter and I don't think you could do the windings and then install them. Cryo treatment is primarily for steel and effects the crystaline structure as part of a tempering process. Don't think it would have much effect on non ferrous copper.

The effects are also turning out to be less then permanent from what I've read. I used to make knives for a living and cryo tempering was all the rage for a while. It seems that the effect starts to fade after five years or so and the material will eventually return to it's original tempered properties but before that it is indeed an interesting process.

Now if you could keep the windings at superconducting cold temps you could probably get some interesting stuff happening but I'm not holding my breath on this one.....

Sailorman!!!! Thanks so much. Exactly the information I was looking for. Thank you. Thank you. Thank you.

Dennis with one less idea to think on....

I also believe that the best possibility for an amazing result would to use the coil while at temps around -300 degrees. Other than that I dont know that the treatment would produce measurable differences in the results of detecting. Some results may be measured with with test equipment, but I wouldnt change your lifes focus. Idigid
