RWTH Aachen University has developed fundamental principles for improved joining methods of hybrid metal and plastic automotive parts under the framework of a Cluster of Excellence. Two different pretreatment methods and three joining processes have been examined and developed under the framework of the Cluster of Excellence, in addition to the untreated test specimens. The two pretreatment methods involve the application of an intermediate plastic coating on the metal part by thermal spraying and laser structuring. Microstructures are produced on the surface of the metallic joint partner during laser structuring, resulting in the development of better hybrid parts. Thermal spraying has been used to heat and melt plastic powder and to apply it to metal parts with high kinetic energy. The pretreatment of a metal specimen by thermal spraying allows those parts to be joined that are unable to be joined without pretreatment.
