The effect of atmospheric pressure cold plasma application on adhesion strength of different materials

Öz

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.

Atmosferik basınçlı soğuk plazma uygulamasının farklı malzemelerin yapışma dayanımına etkisi

Öz

ABSP (Atmosferik Basınçlı Soğuk Plazma) işlemi, polimer ve metal malzemelerin yapıştırma uygulaması öncesinde yüzey özelliklerini geliştirerek istenilen düzeye getirebilmek için yaygın olarak kullanılmaktadır. ABSP, ekonomik ve çevre dostu bir yöntem olup, bu yöntemle malzeme yüzeyleri etkili bir şekilde değiştirilir. Bu çalışmada, polipropilen (PP) ve galvaniz kaplı çelik (H300LAD) malzeme yüzeylerinin modifikasyonu için soğuk plazma yöntemi kullanılmıştır. Uygulama mesafesi ve tarama (paso) sayısı parametrelerinin belirtilen malzemelerin yapışma bağı dayanımları üzerindeki etkisi araştırılmıştır. ABSP uygulama sonrası, malzemelerin yapışma davranışını değerlendirebilmek amacıyla çekme testi kullanılmıştır. ABSP’nin yapışma dayanımı üzerindeki etkisi, temas açısı ölçümleriyle de ilişkilendirilmiştir. ABSP uygulaması sonrası, malzemelerin yapışma mukavemetinde belirgin oranda artış gözlenmiş, malzemeye daha yakın uygulama yapıldığında daha yüksek yapışma mukavemeti değerlerine ulaşılacağı sonucuna ulaşılmıştır.
