The thermodynamical efficiency of heat engines such as gasturbines and diesel engines
can be improved by the application of an increased combustion temperature. To protect the …

Thermal barrier coatings (TBCs) were deposited by an Air Plasma Spraying (APS)
technique. The coating comprised of 93 wt.% ZrO2 and 7 wt.% Y2O3 (YSZ); CoNiCrAlY …

The ceramic top coat has a major influence on the performance of the thermal barrier
coating systems (TBCs). Yttria-partially-stabilized zirconia (YSZ) is the top coat material …

The use of thermal barrier coatings on high-pressure turbine components can improve gas
turbine efficiency through reduction of cooling airflow. However, the risk involved in reducing …

In application as a thermal barrier coating (TBC), partially stabilized zirconia (Zr) approaches
some limits of performance. To further enhance the efficiency of gas turbines, higher …

Thick yttria stabilized zirconia (YSZ) thermal barrier coatings (TBCs) of 1.5 mm thickness
were produced using atmospheric plasma spraying (APS). The microstructures …

The thermophysical and mechanical properties of plasma-sprayed thermal barrier coatings
are very strongly dependent on the microstructure, and this may be controlled by …

The aim of this study is to develop the next generation of production ready air plasma
sprayed thermal barrier coating with a low conductivity and long lifetime. A number of …

Pratt & Whitney has accumulated more than three decades of experience with thermal
barrier coatings (TBCs). These coatings were originally developed to reduce surface …

The 5 layer structured ZrO2–7 wt.% Y2O3–18 wt.% CeO2 (C-YSZ) thermal barrier coatings
(TBCs) by currently Plasma Spray (PS) and functionally graded TBCs system (FG-TBCs) …
