Thermal barrier coatings (TBCs) provide effective thermal barrier to the components of gas turbine engines by allowing higher operating temperatures and reduced cool‐ ing requirements. Plasma spraying, electron-beam physical vapor deposition, and sol‐ ution precursor plasma spray techniques are generally used to apply the TBCs on the metallic substrates. The present article addresses the TBCs f...

A new approach to account for finite thermal conductivity and turbulence effects within atomizing droplets of an evaporating spray is presented in this paper. The model is an extension of the T-blob and T-TAB atomizatiodspray model of Trinh and Chen [9]. This finite conductivity model is based on the two-temperature film theory in which the turbulence characteristics of the droplet are used to ...

Yttrium aluminium garnet (YAG) is a promising topcoat material for thermal barrier coatings due to its high temperature stability and better CMAS (calcium-magnesium-alumino-silicate) resistance. YAG topcoats were deposited by suspension solution precursor high-velocity oxy-fuel (HVOF) spray. The relationships between processing, microstructure final properties studied through range of character...

Abstract Thermal spraying is a scalable surface engineering technique used to add or restore functionality of solid by applying coating. Examples this include protection against wear, erosion, abrasion, and heat. In specific sense, thermal particularly deposit barrier coatings (TBCs) which finds use in transportation, power generation automotive sector. As being technique, much like other coati...
