Abstract

PURPOSE:To clean the surface of metal efficiently, by making uniform cationic stream collide against the whole surface and by making various ion infiltrate into the whole surface by arc discharge without melting base material. CONSTITUTION:Base material pipe 1 made of nonmagnetic material is connected to a cathode, and water-cooled electrode 2 is connected to the anode of an arc source 3 and is inserted into the base material pipe 1. A magnetic coil 4 generates a magnetic field 6 around the pipe 1 by a DC power source 5. High frequency wave of about 10 kHz and low frequency wave of about 10Hz are superimposed on the power source 3. When arc is generated in Ar atmosphere, arc column rotates at a high speed, so that oxide film on the surface is broken. The arc column becomes rigid and constant by the component of high frequency pulse current, and treat the base material surface uniformly by the strong treating power of high peak current. Becauses low frequency wave is applied simultaneously, the speed of the arc column is controlled, arc interruption is prevented, and rise in temp. of base material 1 is also controlled. The whole internal surface is cleaned by moving the base material pipe 1 in the direction of an arrow 7.
