Thermal barrier coatings of Al2O3–ZrO2 were prepared by air plasma spraying on the surface of 20G steel. Phase constitution, microstructures and elemental distributions of the coatings were studied by X-ray diffraction, scanning electron microscope and electron probe X-ray microanalysis. The...

Thermal barrier coatings (TBC) are finding increasing applications in aeronautical, chemical, metallurgy industries, etc. As a ceramic material, ZrO2 is one of the most widely used for TBCs owing to its excellent shock resistance, low thermal conductivity and relatively high coefficient of...

Purpose The application of thermal barrier coatings (TBCs) allows aero-engine blades to operate at higher temperatures with higher efficiency. The preparation of the TBCs increases the surface roughness of the blade, which impacts the thermal cycle life and thermal insulation performance of the...

Thermal Energy Storage (TES) is an important challenge for the development and implementation of Concentrated Solar Power (CSP) plants. The heat can be stored in a sensible, thermochemical or latent form. Recently, the latent heat thermal energy storage (LHTES) kind has gained the most of...

In recent years, there has been an increase in motorization; therefore, the demand for high-efficiency motors in automobiles and aircrafts will further increase. A drone is an aircraft that flies without a human pilot onboard; it has a short flight time because the size of the mounted battery is...

We demonstrate the ability to calculate thermal conductance and elastic properties on three-dimensional images of industrial polymer foamed materials. Results for thermal conductivity and elasticity show little scatter and provide the basis for accurate empirical correlations between phase...
