Summary on Grant Application Form |
|
Design requirements for increasing thrust and efficiency of advanced turbine engines has resulted in a need to extend the temperature capability of existing turbine engine materials. Currently, ceramic thermal barrier coatings (TBC) are specially applied to high pressure turbine blades to maintain acceptable metal substrate temperatures during operation. Development of new coating compatible single crystal Ni-base superalloy compositions with a 30 C temperature improvement over exisiting alloys will enable turbine engines to operate more efficiently with higher operating temperatures.The proposed research (Cranfield + Birmingham + Imperial College) aims to elucidate the mechanisms of TBC failure for current/future TBC systems, based on EB-PVD Zr02-8wt%Y203 ceramic, a platinum diffused bondcoat and single crystal superalloy substrates (CMSX4 + future generation alloys). The programme will examine, bondcoat elastic moduli (Cranfield), oxide growth rates under cyclic conditions and various dwell times (Cranfield, Birmingham, Imperial College), the stress evolution within the TGO (Imperial College), the critical temperature drop to spall (Birmingham), the role of cooling rate (Cranfield), remanant corrosion life (Cranfield), bondcoat erosion resistance (Cranfield). From this understanding/data a predictive model for the life of the TBC/bondcoat/alloy system will be developed (Cranfield) capable of predicting the risk of TBC failure.
