Anisotropic etching of SiC whiskers.
We have demonstrated a method of producing nanoplatelets or complex well-ordered nanostructures from silicon carbide (SiC) whiskers. Preferential etching of SiC whiskers in a mixture of hydrofluoric and nitric acids (3:1 ratio) at 100 degrees C results in the selective removal of cubic SiC and the formation of complex structures resembling a pagoda architecture. Possible mechanisms governing se...
متن کاملMeasurement and simulation of magnetic field strenght in the nano magnetic abrasive finishing process
Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...
متن کاملFlow sensing by pinniped whiskers.
Beside their haptic function, vibrissae of harbour seals (Phocidae) and California sea lions (Otariidae) both represent highly sensitive hydrodynamic receptor systems, although their vibrissal hair shafts differ considerably in structure. To quantify the sensory performance of both hair types, isolated single whiskers were used to measure vortex shedding frequencies produced in the wake of a cy...
متن کاملEffects of Ferrosilicon Addition and Formation of Insitu SiC Nano-whiskers on MgO-C Refractories
Nowadays, SiC is one of the refractory materials which is used widespread because of its unique properties like structural stability in high temperatures. SiC nano whiskers are important in reinforcement of different kinds of composites like ceramic base materials, thanks to their outstanding mechanical, thermal, and chemical properties like low expansion coefficient, high thermal resistant, hi...
متن کاملFracture mechanisms of aluminium cast alloy locally reinforced by SiC particles and Al_2O_3 whiskers under monotonic and cyclic load
In the present paper, fracture mechanisms and corresponding stress distributions in aluminium cast alloy locally reinforced by SiC particles and Al2O3 whiskers under monotonic and cyclic load are investigated experimentally and numerically. The material is monotonically and cyclically deformed to failure at room temperature. The fracture origin and the fracture path are investigated on the frac...
