Thermal Strain-Tolerant Abradable Thermal Barrier Coatings

Journal of Engineering for Gas Turbines and Power, 1991
Thermal barrier coatings (TBCs) are applied to hot gas path surfaces to reduce metal temperatures and thermal stresses for improved turbine component durability. Improvements in engine performance are achieved when TBCs enable reductions in cooling air usage and turbine blade tip-shroud clearances.

Thermal conductivity of thermal barrier coatings

Russian Aeronautics (Iz VUZ), 2009
The results of experimental studies of the thermal conductivity coefficient of thermal barrier coatings (TBC) are presented. A technique for its determination is proposed and tested. The data of design evaluation of the TBC thickness distribution along the outline of a cooled turbine blade are given.

Thermal Conductivity of a Zirconia Thermal Barrier Coating

Journal of Thermal Spray Technology, 1998
The conductivity of a thermal-barrier coating composed of atmospheric plasma sprayed 8 mass percent yttria partially stabilized zirconia has been measured. This coating was sprayed on a substrate of 410 stainless steel. An absolute, steady-state measurement method was used to measure thermal conductivity from 400 to 800 K.

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

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}.

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.
