Using the transient plane source (TPS) technique, the authors investigated the thermal properties of a series of yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBCs). The YSZ coatings had varying amounts of impurities (Zr, Y, Si, Al oxides) and the amount of impurity affected the post-spray ...
Thermal barrier coatings (TBC) are plasma sprayed onto gas turbine parts in order to improve combustion efficiency and component life time. Two TBC are looked at in this report: yttria partially stabilized zirconia (YPSZ) and dysprosia partially stabilized zirconia (DyPSZ). Both the TPS and laser ...
Yttria-stabilized zirconia (YSZ) powders containing varying amounts of SiO2 and Al2O3 impurities were plasma sprayed onto metallic substrates and subsequently investigated. The authors were interested in how the impurities affected sintering rates, thermal conductivity, linear contraction, and pore size and architecture among other things. ...
In order to prepare more thermally resistant materials for use as thermal barrier coatings, the authors performed experiments on yttrium stabilized-zirconia (7YSZ) in order to investigate sintering resistance and phase stability at high temperatures. It was theorized that the main factor that affected the sintering ...
