Protective Thermal Barrier Coatings

2016
The goal of using TBCs is, e.g. to reduce thermal conductivity between exhaust gases and the blade material, anti-corrosion protection and increased wear resistance.

Thermal Barrier Coatings for Superalloys

Superalloys 1980 (Fourth International Symposium), 1980
The current status of ceramic thermal barrier coatings for protection of turbine airfoil components is reviewed. Test results for an early duplex coating system ZrO2-12% Y2O3/Ni-16% Cr-6% Al-0.6% Y, improved system ZrO2-8% Y2O3/Ni-17% Cr-5% Al-0.35% Y, and air/fuel impurity tolerant systems based on ZrO2-8% Y2O3, 2CaO-SiO2, and a MgO-NiCrAlY cermet are

GdPO4 as a novel candidate for thermal barrier coating applications at elevated temperatures

Surface & Coatings Technology, 2018
Extensive efforts are being invested to explore alternative materials to Y2O3 partially stabilized ZrO2 (YSZ) for thermal barrier coating (TBC) applications at elevated temperatures. In this study, GdPO4 is investigated for potential use as TBCs.

Survivability of thermal barrier coatings

Materials Science and Engineering, 1987
Abstract Thermal barrier ceramic oxide coatings are gaining wide acceptance for applications in heat engines. Such ceramic thermal shields are used in conjunction with MCrAlY-type intermediate bond coatings, applied over superalloy substrates. The thermal barrier coatings must endure extreme thermal cycling and hostile chemical environments.

Corrosion-Resistant Thermal Barrier Coatings

Advanced Ceramic Materials, 1988
The corrosion resistance of the zirconia-based thermal barrier coatings to combustion products, such as vanadate and sulfate salts generated in fuel-fired gas turbines, was examined. Investigations have been conducted on the quaternary oxide system ZrO{sub 2}-Y{sub 2}O{sub 3}-SiO{sub 2}-Al{sub 2}O{sub 3}.

Enhancement of hot corrosion resistance of thermal barrier coatings by using nanostructured Gd2Zr2O7 coating

Surface & Coatings Technology, 2019
Improvement of hot corrosion resistance in Na2SO4-V2O5 environments is one of the main goals in development of thermal barrier coatings (TBCs). In this study, nano-Gd2Zr2O7 (nano-GZ) powder was synthesized by co-precipitation method and then deposited ...

Erosion of thermal barrier coatings

Materials at High Temperatures, 2003
AbstractThermal barrier coatings have been used within gas turbines for over 30 years to extend the life of hot section components. Thermally sprayed ceramics were the first to be introduced and are widely used to coat combustor cans, ductwork, platforms and more recently turbine aerofoils of large industrial engines.

Advanced Thermal Barrier Coating

2000
Abstract : The primary research objective of this work was to develop a novel thermal barrier coating (TEC) system by depositing a high quality alpha alumina sublayer on the metallic bond-coat, prior to the deposition of the yttria stabilized zirconia (YSZ) coating.
