Fabrication and inspection of C/Cf-ZrB2-ZrC-SiC and C/Cf-ZrB2-SiC composite parts resistant to ablation by pressureless sintering method
In this research, the aim is to achieve strong and ablation-resistant composite parts C / Cf-ZrB2-ZrC-SiC and C / Cf-ZrB2-SiC by non-pressure sintering method. C / Cf-ZrB2-SiC samples were prepared using synthesized ZrB2 and SiC powders between layers of resin-impregnated carbon fabric. After pressing with pressure 5 times at 1600 وC and heat treatment for 2 hours in a controlled atmosphere fur...
متن کاملThe ZrO2 Formation in ZrB2/SiC Composite Irradiated by Laser
In order to clearly understand the details of ZrO₂ formation during ablation, high intensity continuous laser was chosen to irradiate ZrB₂/SiC. The results reveal that there are two different modes of ZrO₂ formation depending on whether liquid SiO₂ is present. When liquid SiO₂ is present, ZrO₂ generated by the oxidation of ZrB₂ is firstly dissolved into SiO₂. Then, ZrO₂ will precipitate again, ...
متن کاملSynthesis and Sintering of Ti3SiC2–SiC Composites through Reactive Hot-Pressing of TiC and Si Precursors
MAX phases are an attractive class of layered solids that have recently attracted a great deal of attention due to their unusual and unique composition. The ternary compound Ti3SiC2 is an example of a material that combines the properties of ceramics and metals. As a ceramic, they are high stiff. Some of them are resistant to oxidation, creep, fatigue, corrosion. They are extremely refractory a...
متن کاملSimultaneous synthesis and consolidation of nanostructured MgAl2O4- Mg3Al4Ti3O25 composite by pulsed current activated sintering and its mechanical properties
Nanopowders of Al2O3, TiO2 and MgO were fabricated by high energy ball milling. The simutaneous synthesis and sintering of nanostuctured MgAl2O4-Mg3Al4Ti3O25 composite was investigated by the pulsed current activated sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and inhibition of grain growth. A highly dense nanostructure...
متن کاملInvestigation of Glass- Steel Slag Foam Composite Sintering in Presence of SiC
Amorphous steel slag was blended with different concentrations of waste glass (20, 40, 50, 60, 70 wt.%) and SiC to obtain a composite. According to Hot Stage Microscopy images, slag-glass composite contractions started at 1050 ºC. scanning electron microscope micrographs of slag-SiC (foaming agent) composite revealed tunnel-like porosities of 500 to 1000 microns. Gaseous products of carbide dec...
