Efficiency and behavior of textured high emissivity metallic coatings at high temperature

Multilayer multifunctional advanced coatings for receivers of concentrated solar power plants

“…SiC coatings are deposited at 1400 K We carry out our experiments using two solar facilities previously described. The first one is the "REacteur Hautes Pression et Température Solaire" (REHPTS) [12], the second one is the "Moyen d'Essai et de DIagnostic en Ambiance Spatiale Extrême" (MEDIASE) [13][14][15]. Both reactors are located in Odeillo, at an altitude of 1500 m, so that the surrounding atmospheric pressure is 87 kPa.…”

“…The solar concentrated radiation heats the samples placed inside the MEDIASE facility at the focus of the 1 MW solar furnace and previously described [13][14][15]. A CI Systems SR-5000N spectroradiometer measures the normal spectral emissivity on the back face of the sample on a range from 1.4 to 14 µm at various temperatures in the 1100-1600 K interval and these measurements are integrated on the 1.4-2.8 µm and 1.4-14 µm intervals according to equation (1) and 2:…”

Microstructure, radiative property and thermal shock behavior of TaSi2–SiO2-borosilicate glass coating for fibrous ZrO2 ceramic insulation

“…Thus, a high emissivity coating must be designed and prepared on the fibrous ZrO 2 ceramic insulation substrate. Until now, several high emissivity coatings have been developed for the application of thermal protective systems [10,11], thermal furnaces [12] and other high-temperature processing units for the purposes of energy savings [13,14], such as SiC and SiC based composites [6,[15][16][17][18], rare-earth oxides [7,10,[19][20][21], refractory metal silicides [22], transition metal oxides [23,24], cordierite structure systems [25,26], perovskite-type systems [13,27,28], magnetoplumbite structure systems [29][30][31][32] and metallic systems [33,34]. In addition to the pursuit of high M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 5 emissivity, other properties such as thermal shock resistance and oxidation resistance, should also be considered when high emissivity coatings are used at high temperatures.…”

High-performance thermal emitters based on laser-engineered metal surfaces

“…However, for e ective radiative cooling, the broadband emissivity control is preferred. Passive radiative cooling solutions have been intensively investigated for space [12] and high energy applications [13,14] where severe mass and power consumption constraints as well as high operating temperatures are imposed. Textured metallic [12] and ceramic [15][16][17] coatings have been shown as good material candidates exhibiting high emissivity (" 0.8), good temperature and corrosion resistance.…”

However, adhesion, stress resistance and vacuum compatibility of coatings remain a significant concern for applications in high-energy physics and particle accelerators such as the Large Hadron Collider (LHC) at CERN [18][19][20].…”
