CHROMALLOY NEW BARRIER COATING ENHANCES AIRCRAFT ENGINE EFFICIENCY

Chromalloy says its new thermal barrier coating enhances the performance of gas turbine engines. “Chromalloy’s new thermal barrier coating – the RT-35 Low K coating – provides lower thermal conductivity, which allows higher engine temperatures,” said Dr Peter Howard, vice president, technology and quality assurance. 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 RT-35 Low K coating provides
