Abstract
Fabrication of nano-SiC bulk material by selective laser sintering technology with nano-SiC powder is achieved.The microstructure of laser-sintering nano-SiC ceramic coating is examined by means of X-ray diffraction analyses,scanning electron microscopy.At the same time,the laser sintering procedure of nano-SiC powder and effect of technique parameters are investigated.The results show that the nano-SiC powder materials can be sintered to bulk material with the proper process parameters,the crystal size of the production is almost kept the same as that of nano-SiC powder,but some power is decomposed to nano-structural silicon and nano-structural carbon.
