Basic Study of the Peeling Off of Paint Using Irradiation by Atmospheric Pressure Plasma

Previous studies have shown that paint tends to easily peel off when irradiated with plasma. In this study, we use atmospheric pressure plasma irradiation to peel off surface paint. The variable parameters were the applied voltage and the plasma irradiation time. We were able to irradiate the painted surface with atmospheric pressure plasma for 1 min and peel off more than 80% of the paint. It was hypothesized that plasma irradiation affects the internal stress in the painting.
