This study examines the development of aluminium-aluminium
compounds during high pressure die casting. An aluminium insert was mounted into a die casting
mould and embedded into an aluminium casting alloy. Prior to that, the natural oxide layer of the
insert was removed and replaced by zinc coatings with different thicknesses. During the casting
process the zinc layer dissolves and a transition zone with elevated zinc concentration and
hardness forms between insert and casting alloy. The thickness of the initial Zn layer determines
width and composition of the transition zone, but not the mechanical properties of the compound.
The formation of a sound metallic bonding is crucial for the plastic behaviour. (C) 2011 Elsevier
