Thermal Barrier Coatings Capable of High Temperature Operation
ID# 2016-0920
Technology Summary
The disclosed invention is a multiphase ceramic thermal barrier coating. The coating is adapted for use in high temperature applications in excess of 1200°C. It is purposed specifically for coating superalloy components of a combustion turbine engine such as those used in military aircraft, commercial aviation, and power generation.
Application & Market Utility
This novel coating has increased operating temperatures, lower themal conductivity, and lower sintering rate compared to the industry standard (yttria stabilized zirconia). It has a reduced erosion rate over advanced rare earth coatings such as pyrochlores, and has operating temperatures as high as pyrochlore but with significantly increased durability, resulting in more fuel-efficient operation.
