Abstract

See full text

A heat-resistant member includes a base member composed of an isotropic graphite and a film with a single layer or multiple layers formed on the entire or partial surface of the base member. The film includes a dense WC layer with a single layer or multiple layers, and the dense WC layer includes WC as a main component and has a porosity of less than 3%. The film may further include a porous WC layer with a single layer or multiple layers formed on an entire or partial surface of the dense WC layer. In this case, the porous WC layer preferably includes WC as a main component and has a porosity larger than that of the dense WC layer.
