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 کاملسنتز و بررسی خواص نانو پودرکامپوزیتی ZrC-ZrB2-SiC
In this research, ZrC-ZrB2-SiC nanocomposite powder was synthesized by carbothermal and borocarbotermal reduction methods. Zirconium silicate was first milled for four hours Then eight mixtures of raw materials were prepared. Finally, the samples were pyrolyzed at 800 ° C for two hours and then heat-treated at 1500 ° C for 30 minutes under an argon atmosphere. X-ray diffraction (XRD) and scanni...
متن کاملC/C-ZrB2-ZrC-SiC Composite Derived from Polymeric Precursor Infiltration and Pyrolysis Part 2: Mechanical and Ablation Properties
Mechanical and ablation properties of the 2D C/C-ZrB2-ZrC-SiC composites with a fiber volume fraction of 17.6%, fabricated by infiltration and co-pyrolysis of blended polymeric precursors, were studied in this Part II. Flexural strength and fracture toughness of the composites were found to be influenced strongly by the thickness of the deposited pyrolytic carbon interphase, a composite with th...
متن کاملThe Effect of the Mg Content on Mechanosynthesis of ZrB2–SiC–ZrC Composite in the Mg/ZrSiO4/B2O3/C System
The influence of magnesium content on the mechanosynthesis of ZrB2–SiC–ZrC composite in Mg/ZrSiO4/B2O3/C mixture was investigated. Thermodynamic evaluations revealed that the amount of Mg played a main role, thereby; the overall reaction enthalpy and adiabatic temperature (Tad) changed by variation of magnesium content. According to differential thermal analysis (DTA) results, after 45min milli...
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, ...
