Surface Modification of Metallic Inserts for Enhancing Adhesion at the Metal–Polymer Interface

A combination of mechanical and chemical treatments was utilized to modify the surface textures of copper and duralumin inserts in order to enhance the adhesion at the metal–polymer interface and provide an adhesive joint with a high loadbearing capacity. Pretreatment of the surfaces with sandblasti...
