In this paper, ultrasonic vibration–assisted electrical discharge machining (UEDM) is used to process SiCp/Al composite materials in order achieve a higher material removal rate (MRR) and lower surface roughness, width overcut, relative tool wear (RTWR). On the basis of studying erosion mechanism EDM material, flow field simulation study was carried out using FLUENT software. The results gap sh...

This paper studies the milling process of SiCp/Al2024 composite with high volume fraction and large particle size. The mechanism is analyzed. influence cutting depth feed per tooth on surface quality It reveals subsurface damage workpiece. results show that in composite, because edge radius much larger than radius, main form removal crushing. defects workpiece mainly include pits, cracks, scrat...

Abstract After powder metallurgy and carbon/carbon brake materials, carbon-ceramic material (C/C-SiC) is a new generation of braking material. There are currently some batches materials whose friction performance could be better: slightly higher than the standard. SiC was introduced into C/C-SiC disc through Polymer Impregnation Pyrolysis (PIP), composition friction-wear C/C-SiC-SiCp were inves...
