Ceramic thermal barrier coatings with improved corrosion resistance
Conference

OSTI ID:6419775
A method for limiting the ingress of corrosive species into physical vapor deposited zirconia thermal barrier coatings by inserting dense ceramic sealing layers into the usual columnar (segmented) ceramic microstructure has been examined. The concept was evaluated by sputtering a series of ZrO/sub 2/-2OY/sub 2/O/sub 3/ deposits onto In792 substrates coated with a CoCrAlY bondlayer.
