SURFACE TREATMENT METHOD AND CORONA DISCHARGE TREATMENT DEVICE

摘要

A surface treatment method, comprising the steps of covering either of first and second electrodes disposed close to each other with an insulator, and installing the first and second electrodes close to the treated surface of a treated material so that even a non-conductive thick large material can be surface-treated efficiently, whereby the treated surface can be modified by bringing a corona discharge generated by applying a high-frequency high-voltage across the electrodes into contact with the treated surface of the treated material.
