Considerable work has been carried out on overlay bond coats in the past several decades
because of its excellent oxidation resistance and good adhesion between the top coat and …

In this paper, the residual stress of double-ceramic-layer (DCL) La2Zr2O7/8YSZ thermal
barrier coatings (TBCs) fabricated by atmospheric plasma spraying (APS) was calculated by …

This paper studies how the nano-mechanical properties of thermal barrier coatings (TBCs)
vary during thermal cycling, as a way to shed new light on their failure mechanisms. In …

Thermal barrier coatings (TBCs), when used in gas turbines, may fail through thermal
fatigue, causing the ceramic top coat to spall off the metallic bond coat. The life prediction of …

The coefficient of thermal expansion (CTE) of nickel-based superalloys and bond coat layers
was modelled by considering contributions from their constituent phases. The equilibrium …

Demand for economically efficient and environmental friendly gas turbine engines leads to
the usage of a thermal barrier coating (TBC) system, which is usually sprayed on the top of a …

Abstract Failure in Atmospheric Plasma-Sprayed (APS) thermal barrier coatings (TBCs) is
associated with the thermo-mechanical stresses developing due to the thermally grown …

Abstract Thermal Barrier Coatings (TBC) are widely used to protect the metallic components
that operate at harsh conditions of elevated temperatures and oxidizing environments …

Thermally grown oxide (TGO) is a critical factor for the service life of thermal barrier coatings
(TBC). Numerical simulations of the growth process of TGO have become an effective …

This article describes a method of predicting the failure of a thermal barrier coating system
due to interfacial cracks and cracks within bulk coatings. The interfacial crack is modelled by …
