...-making experiment of UVHG was conducted, and the contact behavior between a grain and different components in the SiC f /SiC was analyzed. The evaluation index of the hole wall quality C w which comprehensively considers the overall level and local defects of surface quality was proposed, while...

... techniques, is able to fabricate complex geometries with superior material properties. However, due to the poor surface quality, the fabricated internal surfaces cannot meet the specifications for some real applications. To achieve the required internal surface condition, post-polishing process is essential...
