ABSTRACT:
For the production of a shaped body of graphite with a reaction-bound Si/SiC coating it is proposed to bring the shaped body--provided with a slip layer of a homogenized mixture, heated and gassed under vacuum with gaseous silicon or impregnated with liquid silicon--to a form of predetermined dimensions. To this end the shaped body is treated after the coating by cutting or brushing or by electronically controlled laser erosion or by several of these measures.
