Die casting is a common industrial process for the production of complexly shaped products made of light metal alloys. However, the adhesive processing of die-cast aluminium components is fraught with a number of challenges. Among other things, the alloy composition and the coating with release agents can have a negative influence on the adhesive bond to the component surface as well as its resistance to ageing and corrosion. Depending on the position on the component, both influencing factors can show significant differences in their characteristics, so that the adhesion suitability for each joining position must be carefully examined.
The aim of this thesis is to investigate the influence of release agent assignments and element distribution on the local suitability for adhesion of aluminum die-cast components. For this purpose, a literature search on the basics of adhesive bonding of aluminium die casting must first be carried out. In the experimental part, tests are to be carried out with the preparation of adhesive bonds, tensile shear tests and the subsequent analysis of the fracture patterns of the bonds. In addition, material investigations are planned to determine the local element distribution and the release agent occupancy. The results of these investigations are to be correlated with the varied casting process parameters.
