Abstract:

ABSP (Atmospheric Pressure Cold Plasma) process is widely used in order to improve the surface properties of polymers and metals before the bonding application and bring them to the desired level. ABSP is an economical and environmentally friendly method and the material surfaces are changed effectively. In this study, cold plasma method was used for the modification of polypropylene (PP) and galvanized steel (H300LAD) material surfaces. The effect of process parameters such as application distance and number of passes on the adhesion bond strength of the specified materials was investigated. After ABSP application, tensile test was used to evaluate the adhesion behavior of the materials. The effect of ABSP on adhesion strength was also correlated with contact angle measurements. After ABSP application, a significant increase was observed in the adhesion strength of the materials, and it was concluded that higher adhesion strength values would be achieved when the application was made closer to the material surfaces.
