Technology Marketing SummarySandia has developed a method and apparatus for depositing thermal barrier coatings on gas turbine blades and vanes which increase the thermal resistance of the blades and leads to higher efficiency. Higher operating temperatures for gas turbine engines are continuously sought in order to increase their efficiency.DescriptionCeramic thermal barrier coatings (TBCs) have been used since the 1970’s to protect gas turbine blades from oxidation and corrosion. A lower thermal conductivity is desirable in order to increase component lifetimes by allowing a thinner, lighter ceramic coating to be used. Sandia’s method and apparatus for depositing thermal barrier coatings reduces the total processing time which greatly reduces costs by increasing throughput rates. Up to 12 hours of processing time could be saved by using this improved method.  This technology is only available to companies who can combine Ion Beam Assisted Deposition (IBAD) with Electron Beam Physical Vapor Deposition (EBPVD).
