Since 1999, we have been exploring deep cryogenics to understand how and why it works and where it is most effective. But first of all, what is it?
Deep cryogenics is a -310° F cold treatment process that has been proven to permanently reduce wear, fatigue and corrosion by 20-70% in metal, metal-matrix and additive manufactured items by altering atomic-level grain structures (see MIT tech briefing).
What is the deep cryogenic process?
Items are placed in an insulated tank. The tank is surrounded by an outer jacket filled with liquid nitrogen. The inner tank temperature drops slowly as heat is removed from the items by thermodynamic exchange. Once the desired temperature is reached — processes or "recipes" vary for different metals — the items remain in this subzero state before gradually ramping back up to room temperature. Then they are tempered to eliminate hydrogen embrittlement (a cause of corrosion). During this process, the liquid nitrogen transforms into a gas and returns naturally to the atmosphere, where it comprises 78% of the air we breathe. Deep cryogenic treatment takes between 24 and 70 hours, and it is inexpensive, safe and uses no toxic chemicals.
Although popularized by consumer use in motor sports, electronics, firearms and tooling, the process has its greatest opportunity in extending the life and performance of moving platforms such as planes, cars, ships, trains — all of which are subject to constant wear, fatigue, corrosion and environmental breakdown. Other key opportunities exist in oil and gas drilling and sub-sea equipment, additive manufacturing, gas turbine and wind power generators, electric vehicle gears and industrial bearings.
Here's a reasonable question: Why has deep cryogenics never received mainstream attention and acceptance?
For a number of reasons, among them:
Deep Cryogenics International is dedicated to making things last longer™ — specifically metal and metal-matrix items — by exploring and advancing the deep cryogenic process.
We provide cutting-edge scientific research and deep cryogenic treatment, particularly at the intersection with additive manufacturing. Our discoveries will serve many discrete players: corporations with competitive advantage, individuals with longer lasting products and the environment by reducing "throwaway" obsolescence. These goals are interwoven in each of our daily choices — whether we drive a car, turn on the heat, purchase something we want or use what we value.
