Abstract
An exhaust device whose inner surface is coated with a heat-insulating layer and a refractory layer. Each layer is formed by conducting at least one cycle of the steps of: (a) coating the inner surface with an inorganic binder solution, (b) immediately adhering a coating powder to the binder solution layer so that the powder is fully and uniformly impregnated with the binder solution, and (c) drying and solidifying it by heat treatment. The coating layer does not suffer from cracking, peeling and breakage.
