This article presents preparation of near-eutectic aluminum-silicon surface
(AC-AlSi11) by anodic oxidation, which produces a porous oxide layer (Al2O3) substrate
constituting the permanent adhesive connection with an epoxy composition. Documents
influence of silicon educe in the form of unmodified alloy (AC-AlSi11) and modified
(AC-AlSi11 + M) in the anodizing process, uniform structure and thickness of the oxide
layer and the topography of the surface to improve adhesion of the resin to AlSi alloy
This paper also describes the influence of the oxidized surface position in relation to the
negative electrode i to the coating. In assumption elements of the test spatial castings will
change the distribution of the electric field h resulting in a heterogeneous structure of the
coating. The effect of surface preparation by oxidation on the mechanical properties of
the connection AlSi alloy-resin is also described. The motivation for this study was a new
group of products - spatial skeleton castings in which by regulation and prediction of
effects at the border of the contact between ceramic and casting has influenced on
structural and mechanical properties of cast skeleton composites.
