Abstract

Aluminum–aluminum compound castings consisting of an aluminum wrought alloy sheet
and an aluminum casting alloy are produced via high pressure die casting (HPDC). In
order to realize a firm bonding, the sheet material is Zn‐coated prior to casting.
The task of the Zn‐coating is to replace the resistant aluminum oxide layer on the
surface. In addition, a smooth metal–metal interface between the insert and the casting
alloy develops by the diffusion of Zn atoms into the surrounding area of the interface.
Within this paper, the subsequent heat treatment of the resultant formation is investigated
to enhance the strength of the firmly bonded compound. In a first step, heat treatment
for two wrought alloys AlZn5.5MgCu, AlCu4MgSi, and the casting alloy AlSi10Mg(Fe)
are examined. Based on these results, suitable parameters for the heat treatment of
the compounds are selected and tested. Mechanical tests demonstrate a significant
enhancement for the strength of the heat treated compounds. Microprobe analysis is
used to examine the diffusion and dissolution of the coated Zn at the boundary layer
during the solution annealing of the firmly bonded compound.
