Thermal and mechanical performance evaluations of sliding systems are required to avoid the failure surfaces due high temperature a stress focus on small contact area. This work investigates thermal tribological an epoxy composite reinforced with zirconium diboride (ZrB2) polytetrafluoroethylene (PTFE) particles. Three-dimensional finite-element models used study heat generated (heat flux), fie...

Ultra-high temperature ceramic matrix composites (UHTCMCs) are a new class of which combine boride phases with carbon fibres to achieve structural and functional properties were originally designed for aerospace applications. For the first time, this work investigates optical response UHTCMCs in view their possible application as high solar absorbers Concentrating Solar Power systems. Carbon fi...

Ultra-high temperature ceramics have been considered as good candidates for plasma facing materials due to their combination of high melting point, strength and hardness, thermal conductivity well chemical inertness. In this study, zirconium diboride has chosen investigate its irradiation damage behavior. Irradiated by 4 MeV Au2+ with a total fluence 2.5 × 1016 cm?2, ceramic shows substantial r...

Materials have been selected for the shim rods and burnable absorbers to compensate excessive reactivity of facility’s blanket part provide possibility control in conjunction with a plasma source neutrons. Burnable absorber is layer zirconium diboride (ZrB 2 ) thickness 100 μm applied surface fuel compacts. Boron carbide (B 4 C) installed helium flow channels used bring entire system into state...
