Cool Brake Treatment Nets Hot Results

OGDEN, Utah--A “cold” treatment process from Cryocon Inc. has been rated a hot success when applied to Down Under brake rotors.

Disc Brakes Australia (DBA as DBA), headquartered in Silverwater, Sidney, has begun testing with Cryocon’s proprietary Deep Cryogenic Tempering (DCT) technology on its brake rotors. (DBA markets rotors in 11 countries. In 1999, it won the Australian Automobile Aftermarket Association’s Best New Product Award for specialty rotors designed for high impact vehicles.)

The company intends to improve rotor wear life and overall rotor performance. “Current field testing (has resulted in) at least a 350 percent gain in wear life as well as a decrease in warping and damage due to heat checking,” according to Robert W. Brunson, Cryocon’s president and chief executive officer.

DCT is a computer-controlled tempering process that significantly improves the wear and performance characteristics of many types of metals, alloys, and synthetic materials. Treated items show dramatic increases in wear resistance, toughness, machinability, thermal stability and dimensional stability, he said.

DCT utilizes liquid nitrogen that is flashed to a gas to achieve temperatures minus 300 degrees Fahrenheit. “This technique is completely dry and eliminates the condition known as thermal shock, which is a problem related to traditional cryogenic applications involving spraying or dipping,” he explained.
