Abstract
The present invention relates to a coating method for a plasma block and a plasma block coated by the same. The method comprises processing two sub-blocks capable of being coupled to each other for forming a flowing path; coating the flowing path of one sub-block by injecting an electrolytic solution to the flowing path after displacing an electrode within the flowing path; coating an outer surface of the one sub-block; and coating the other sub-block in the same manner as applied to the one sub-block.
