The Chromalloy RT-35 Low K coating was patented 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. It 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 during operation. In addition, the coating increases the oxidation and corrosion resistance of the underlying bond coating as it is cooler and thus extends the life of the engine components – another cost saving for the operator.
