ELECTRIC ARC SPRAYING APPARATUS

摘要

PURPOSE: An electric arc spraying apparatus is provided to conveniently coat a base material with a spraying method. CONSTITUTION: An electric arc spraying apparatus comprises a wire rod feeding part (2), a spraying part (4), and a mask part (6). The wire rod feeding part moves two wire rods in one direction so that the front end of the wire rods can be melted by arc discharge. The spraying part is arranged corresponding to the wire rods of the wire rod feeding part and sprays the molten metal toward a base material. When the spraying part sprays the molten metal, the mask part forms a coating layer and a non-coating layer on the base material.
