Effect of metal surface state on injection joining strength of aluminum-rubber composite part

摘要: Abstract Metal–rubber composite parts with characteristics of high elasticity and compressibility are widely used in seal vibration resistance engineering fields. The injection technology was proposed to mold metal – rubber parts. With pretreatments anodization silane coupling agent, the morphology composition Al surface were changed, then - fabricated by technology. effects morphologies compositions induced different conditions agent discussed. scanning electron microscopy (SEM) X-ray energy spectrum analyser (XPS) examination proved that microstructures hydroxyl groups formed on contribute significantly bonding strength interface. Furthermore, effect temperature between investigated. By increasing 120 °C, improved more than twenty folds compared lower case. Results showed molded exhibit excellent tensile shear strength, exceeding shearing itself. presented method can be promoted related
