Polar Cryogenics is a small start- up company that does
cryogenic tempering of metals. When the Wright Technology Network (WTN)
first started working with them they were located in the Hamilton County
Business Facility, an incubator located in Cincinnati, Ohio. Polar
Cryogenics subsequently outgrew the incubator and in the fall of 1998 moved
to their present location in Batavia, Ohio. Their process has proven very successful in extending the
useful life of metals by making them both more wear and fatigue resistant.
The company feels that their process is unique and is planning to file a
patent application. Polar Cryogenics knows the results of their
process, but would like to better understand the physical changes that occur
during the tempering process. This information would also assist
greatly in obtaining patent protection for their proprietary process.
Technology specialists from WTN
and software experts from the Air Force Research Laboratory Materials and Manufacturing
Directorate (AFRL/ML) visited the Polar Cryogenics production facility and reviewed their
process and equipment. It was decided that the AFRL scientists could
provide Polar Cryogenics the most help by taking samples of the composite
metals which were being cryogenically tempered and try and determining what
physical changes, if any, were being caused by the tempering process.
AFRL metallurgists are in the process of examining samples of the composite
metals before and after cryogenic tempering to determine what structural
changes are taking place.
- Enhanced wear characteristics in metals.
- The Air Force would
benefit from learning about possible new methods of treating metals that
could make them more wear and fatigue

- Air Force
experts have polished metal samples provided by Polar Cryogenics.
in the process of examining them with the aid of an electron microscope.
- A report of their findings is scheduled
to be completed in the first quarter of 1999.
