DEVICE OF TREATING SURFACE OF INNER WALL OF PIPE BY DIFFUSION OF DYNAMIC PLASMA

摘要

PURPOSE: A device of treating the surface of an inner wall of pipe by the diffusion of a dynamic plasma is provided to treat uniformly the surface of an inner wall of a cylinder shaped pipe and to control the degree of surface treatment by using the dynamic characteristic of a plasma. CONSTITUTION: A device of treating the surface of an inner wall of pipe by the diffusion of a dynamic plasma comprises : a central electrode(c) of the same axle ; a current introduction electrode(a) to form a circular plate shaped tip ; a circular plate shaped pipe(s) to be contacted with a circular plate shaped current introduction electrode(a) and to form a vacuum tool and a part of an electrode ; an electrode for revolving current(b) to be contacted with one side of a circular plate shaped pipe(s) and to be connected with a central electrode(c).
