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: - Production of UHTCs based on ZrB 2 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.) - Advanced 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. - Development of gradient coatings based on the selected UHTC compositions over metallic and non- metallic substrates. - Advanced performance characterization of the developed gradient coatings under relevant service conditions. The present Deliverable 4.3 foresees the dispatch of ceramic powder batches from CNR (Italy) to TECNALIA (Spain) to test the feasibility of two spray techniques: Shrouded Plasma Spray and High Frequency Pulse Detonation.

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: - Production of UHTCs based on ZrB 2 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.) - Advanced 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. - Development of gradient coatings based on the selected UHTC compositions over metallic and non- metallic substrates. - Advanced performance characterization of the developed gradient coatings under relevant service conditions. The present Deliverable 4.3 foresees the dispatch of ceramic powder batches from CNR (Italy) to TECNALIA (Spain) to test the feasibility of two spray techniques: Shrouded Plasma Spray and High Frequency Pulse Detonation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
