This paper reviews protective coatings against the high temperature oxidation and corrosion
of gas turbine components. Having briefly reviewed the development of gas turbine …

Over the years, diffusion aluminide bond coats have been widely used for providing
oxidation resistance to Ni-base superalloy components of advanced gas turbine engines …

Surface engineering is now a key materials technology in the design of future advanced gas-
turbine engines. This article focuses on coating systems for hot-gas-path components, which …

Thermal barrier coatings (TBCs) have been in use in aeroturbine engine hot sections for
over 20 years. The initial applications were driven by the need to suppress component …

Whether an airplane or a space shuttle, a flying machine requires advanced materials to
provide a strong, lightweight body and a powerful engine that functions at high temperature …

The influences of S, Pt, and Hf on the oxidation behavior of chemical vapor deposition (CVD)
NiAl bond coatings on high-S and low-S superalloys were investigated. Cyclic and …

The thermal expansion mismatch between a metallic substrate and its external oxide scale
generates a strain on cooling that is a primary cause of spallation of protective oxide scales …

The martensitic phase transformation in single-phase β-NiAl and (Ni, Pt) Al coatings was
investigated. After isothermal exposure to 1150° C for 100 h, the β phase in both types of …

We investigate with first-principles density functional theory (DFT) the adhesion of the Al2O3
(0001)/NiAl (110) interface as a model for the thermally grown oxide/bond coat alloy …

Iron-and Ni-base alloys, with and without Hf or Hf and Y alloy additions, were aluminized by
chemical vapor deposition to study the potential for minor alloy additions to improve …
