Chromalloy released that its new thermal barrier coating enhances the performance of gas turbine engines. The RT-35 Low K coating was patented by Chromalloy in 2006 and certified by the Federal Aviation Administration (FAA) in 2010 for use on the PW4000 second stage high pressure turbine blade after a series of tests confirming its low thermal conductivity, high thermal cycle durability and other attributes. The coating is currently in use by a commercial airline in Asia. The RT-35 Low K coating provides a layer of insulation to the base metal component and underlying bond coating surface of a turbine blade from the extreme heat of the combustion gases during engine operation. "The coating provides 50% lower thermal conductivity, allowing engines to perform at higher temperatures," Dr. Peter Howard, Vice President, Technology and Quality Assurance said. "Engines produce greater thrust when operating at higher temperature
