Cryogenics is a branch of physics that studies very low temperatures (Kelvin Scale), how to produce them, and how materials behave at those temperature. Cryogenics is often misinterpreted as being the same as cryonics and/or occasionally cryobiology.

Mode of Action
Based on a pre-determined thermal cycle that involves cooling of the tools/parts in a cryogenic chamber, materials are cooled to cryogenic temperatures with nitrogen gas, utilizing precisely controlled temperature profiles.
Applications
There are few limits as to where cryogenic benefits can be applied, specifically for industial purposes. Welding is a good example of an industrial application that can benefit from cryogenic treatment. Copper electrodes used for welding exhibit longer life, show less wear and deformation, and they can be used with less power input.
Longevity of Components
Cryogenically treated materials show a marked increase in wear resistance without any discernable change in dimensional or volumetric integrity. Machining treated material is easier and cleaner. Redressing or regrinding treated tools removes less stock material resulting in longer tool life.
Increasing Mileage
"I've been involved with cryo engine treatment (and other components) since 1998. NASCAR has been doing this for years -- especially brake rotors ... as have Police agencies around the Country." -- D.L., Tennessee
David Hutchison says his cryogenically tempered Carnot-cycle internal combustion engine car has been known to get close to 120 miles a gallon.(However, mainstream engineers and scientists say that this is not likely. Fuel efficiency is governed by thermodynamic laws about how much work energy a process can get out of a given amount of thermal energy or "heat". Thermal energy is more valuable, or useable, when there is a greater temperature difference. A 250-degree-Celsius heat source for a Carnot cycle engines operating on a mild 27-degree-Celsius day could never exceed 43% efficiency. And that's for a perfect engine. The Second Law of Thermodynamics prohibits it.)

- Cryogenics boosts mileage and component longevity - David Hutchison treated his Honda Hybrid engine components to -300ยบ F. Says his mileage went from 50 to 120mpg. The low temp causes a re-alignment of the molecules into a more sturdy state. He also treated his break rotors to make them last 3-5 times longer. Engine components also expected to last that much longer. NASCAR has caught on. (KFOR; Oklahoma; May 25, 2005) ... max mpg at 45 mph flat road.from pre 50mpg to 60 mpg after treating, on average.
