SURFACE TREATMENT APPARATUS AND METHOD USING ATMOSPHERIC PRESSURE PLASMA FOR PLATING PRETREAMENT OF MATERIAL HAVING HARD SURFACE TO PROVIDE CONVENIENT PROCESS

摘要

PURPOSE: To improve plating capability and provide process convenience by treating the surface of a material having hard surface using atmospheric pressure plasma as a plating pretreatment process. CONSTITUTION: The surface treatment apparatus comprises a hollow body (12) comprising an inflow port (24) for flowing in gas; first electrode (14) installed on an upper part of the body; second electrodes (18) comprising a plural exhaust holes (18a) circulated to the outside with being installed under the first electrode at positions spaced apart from the first electrode in a certain distance; and a power supply unit for impressing a power supply to the first electrode and second electrodes, wherein the surface of a material having hard surface is treated by injecting plasma generated by impressing a power supply to the gas flown in the inflow port through the first electrode and second electrodes onto the material through the exhaust holes of the second electrodes, wherein the surface of a hard surfaced material having large area is treated by controlling size of the first electrode and the second electrodes according to area of the hard surfaced material.
