バニシング加工によるグラファイトの鏡面加工

抄録

Graphite is one of carbon materials and it has excellent characteristics such as lightweight, electrically conductive and heat resistance. Therefore, graphite is used for many productions (an electrode for electrical discharge machining and a melting pot). However many air bubbles are existed during fabrication by sintering a powder of carbon. Air bubbles obstruct to manufacture graphite mirror surface. This paper indicates to the method making mirror surface on graphite by burnishing for removing air bubbles.
