摘要：
Cold rolled steel sheet for automotive was treated by Ar/O-2 atmospheric pressure plasma to improve the adhesive bonding strength. Through the contact angle test and calculation of surface free energy for cold rolled steel sheet, the changes of surface properties were investigated before and after plasma treatment. The contact angle was decreased and surface free energy was increased after plasma treatment. And the change of surface roughness and morphology were observed by AFM(Atomic Force Microscope). The surface roughness of steel sheet was slightly changed. Based on Taguchi method, single lap shear test was performed to investigate the effect of experimental parameter such as plasma power, treatment time and flow rate of 02 gas. Results shows that the bonding strength of steel sheet treated in Ar/O-2 atmospheric pressure plasma was improved about 20% compared with untreated sheet.
