<p>PURPOSE:To make it possible to form a coating layer only to the predetermined area of a hot wire, by a method wherein a slurry is made to flow down from the opening part provided to an electrophoretic cell 3 and the hot wire is inserted in the slurry to perform electrophoresis. CONSTITUTION:A slurry 11 is injected in an electrophoretic cell 3' from a slurry injection port 3 until and electrode 5 is immersed in the slurry and made to continuously flow down from an opening part 2. Next, the part to be coated of the hot wire 13 fixed to a U-shaped jig 12 is inserted in the slurry stream flowing down from the opening part 2 and a jig 12 is connected to a DC power source 6. By this method, the dispersed particles in the slurry 11 are moved to the hot wire 13 to adhere a carrier or a carrier with a catalyst to the required place of the hot wire 13. The slurry 11 flowing down from the opening part 2 is received in a mixing tank 7 in which the slurry is similarly charged and mixed by a magnetic stirrer 10. Further, the slurry of which the amount is same to that of the slurry having flowed down from the opening part 2 is returned to the cell 3' from the mixing tank 7 by a pump 8 through a recirculation line 9.</p> |
