T1 INVESTIGATION OF IN-FLIGHT PARTICLE CHARACTERISTICS AND MICROSTRUCTURAL EFFECTS ON OPTICAL PROPERTIES OF YSZ PLASMA-SPRAYED COATINGS JF High Temperature Material Processes: An International Quarterly of High-Technology Plasma Processes JO HTM YR 2007 FD 2007-11-26 VO 11 IS 3 SP 309 OP 320 AB The purpose of this study is to investigate the microstructural effects of yttria-stabilized zirconia (YSZ) plasma-sprayed coatings on their optical properties in order to improve the thermal performance of these coatings that are often used as thermal barrier coatings (TBCs). Four coatings with significant microstructural differences have been manufactured. A preliminary investigation of in-flight particle characteristics has been performed to select the spray conditions. This investigation used two complementary particle diagnostic tools: the DPV2000 system and a particle collection device. Both hemispherical transmittance and reflectance spectra of the coatings have been investigated over the 0.25−10 μm wavelength range. The Gouesbet-Maheu four-flux model has been implemented to calculate the absorption and scattering coefficients. Their variations are discussed in terms of microstructural effects.
