Thermal Barrier Coatings for Gas-Turbine Engine Applications
TL;DR: In this article, the structure, properties, and failure mechanisms of thermal barrier coatings (TBCs) are reviewed, together with a discussion of current limitations and future opportunities.
Journal ArticleDOI
Thermal barrier coatings for aircraft engines: History and directions
TL;DR: In this article, thin thermal barrier coatings (TBCs) for protecting aircraft turbine-section airfoils are examined, focusing on those advances that led first to TBC use for component life extension and more re-cently as an integral part of airfoil design.

Thermal expansion study of plasma-sprayed oxide coatings
TL;DR: In this article, the thermal expansion properties of overlay coatings are investigated under different conditions of coating-substrate adherence and on coatings that were substrate free, and the effects on the expansion coefficient of variations in composition, porosity, heating rate and thermal cycling are investigated.

Effect of thermal cycling on ZrO2Y2O3 thermal barrier coatings
G. Mcdonald,Robert C. Hendricks +1 more
TL;DR: In this paper, a study was made of the comparative lifetimes of plasma-sprayed ZrO 2 Y 2 O 3 thermal barrier coatings on Rene 41 in short and long thermal cycles to 1040°C in a 0.3 Mach flame.

The role of thermal shock in cyclic oxidation
TL;DR: In this paper, the effect of thermal shock on the spalling of oxides from the surfaces of several commercial alloys was determined, and the average cooling rate was varied from approximately 240°c/sec to less than 1.0°C/sec during cyclic oxidation tests in air.

The cyclic oxidation resistance of cobalt chromium-aluminum alloys at 1100 and 1200 C and a comparison with the nickel-chromium-aluminum alloy system
TL;DR: In this article, a series of Co-rich alloys in the Co-Cr-Al system were cyclically oxidized in still air for 500 1 -hr heating cycles at 1100° C and 200 1-hr heating cycle at 1200°C.
