The LIGHT-TPS project will develop light complex TPS for future reusable space crafts and hypersonic aircrafts, which will combine elements made of various heat-resistant materials depending on the level and distribution of thermal and aerodynamic load on the surface of the vehicle. The goals of the fourth work package are: oProduction of UHTCs based on ZrB2 containing various amounts of SiC and sintered with different agents, possessing microstructural features miming those typically obtained by coating (porosity, mean grain size, secondary phase distribution, etc.) oAdvanced characterization of selected UHTC compositions, including the characterization of thermo-mechanical properties, oxidation resistance in the temperature range 1000- 1600°C and the in deep characterization of the degradation mechanisms in highly corrosive streams. oDevelopment of gradient coatings based on the selected UHTC compositions over metallic and non-metallic substrates. oAdvanced performance characterization of the developed gradient coatings under relevant service conditions. The present Deliverable 4.1 provides an overview on the ceramic materials produced by CNR (Italy) and IPMS (Ukraine), on their microstructural features and on the preliminary thermo-mechanical properties.

Abstract
The LIGHT-TPS project will develop light complex TPS for future reusable space crafts and hypersonic aircrafts, which will combine elements made of various heat-resistant materials depending on the level and distribution of thermal and aerodynamic load on the surface of the vehicle. The goals of the fourth work package are: oProduction of UHTCs based on ZrB2 containing various amounts of SiC and sintered with different agents, possessing microstructural features miming those typically obtained by coating (porosity, mean grain size, secondary phase distribution, etc.) oAdvanced characterization of selected UHTC compositions, including the characterization of thermo-mechanical properties, oxidation resistance in the temperature range 1000- 1600°C and the in deep characterization of the degradation mechanisms in highly corrosive streams. oDevelopment of gradient coatings based on the selected UHTC compositions over metallic and non-metallic substrates. oAdvanced performance characterization of the developed gradient coatings under relevant service conditions. The present Deliverable 4.1 provides an overview on the ceramic materials produced by CNR (Italy) and IPMS (Ukraine), on their microstructural features and on the preliminary thermo-mechanical properties.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
