Air Products' New Thermal Spray Cooling Technology Takes off with Delta Air Lines


R&D Collaboration Leads to Industrial Gas Contract Win

LEHIGH VALLEY, Pa., April 14 - Air Products' (NYSE:APD) new Thermal Spray Cooling Technology - which uses cryogenic nitrogen vapor (-320 degrees Fahrenheit) to maintain part temperature during thermal spray coating applications - is enabling Delta Air Lines, Inc. to apply quality coatings on critical aircraft parts more effectively and economically than with traditional methods. Additionally, the success of this technological collaboration assisted Air Products in winning a contract to supply Delta's Technical Operations Facility in Atlanta, Ga. with all of its bulk nitrogen, argon, oxygen and hydrogen needs.

"Delta gave us parameters on how they wanted the machine to think and act, and we designed a thermal spray cooling system to meet their specifications," said Matt Thayer, senior principal engineer, Commercial Technology at Air Products.

Air Products' Thermal Spray Cooling Technology is an automated cryogenic gas cooling system that is being used by Delta's HVOF (high velocity oxygen fuel) thermal spray department to coat critical wear parts, such as rotating engine parts and landing gear. By eliminating the need for inter-pass cooling breaks, the Air Products cooling system has enabled Delta to reduce by as much as 50 percent the spray-coating time, amount of feed powder sprayed, and the volume of gases consumed in the coating of its landing gear axles.

Air Products' U.S. patent-pending cooling technology also offers environmental and product quality improvements. The technology has enabled a tungsten carbide cobalt coating to be more cost-effectively substituted for traditional chrome plating, which can generate a potential carcinogen at high temperatures. In addition, the new technology minimizes the undesired thermal softening of coated parts by reducing the temperature fluctuations and the duration of the coating process.

"This is another great example of what Air Products does best," said Thayer. "We listen carefully to our customers so we can understand their challenges and needs, and then work closely with them to find a solution. We look forward to working with Delta on this emerging technology by continuing to improve it and expand its use within their facility."
