Purpose: This elaboration presents the influence of casting method and anodic treatment parameters on thickness and structure of an anodic layer formed on aluminium alloys. As test materials it was employed the aluminium alloys AlSi12 and ALSi9Cu3, supplied by the Dutch company MIFA b.v., in which casting process and anodic treatment of samples were carried out also. It was presented herein grindability test results and metallographic examination, as well. Hardness of non-anodised alloys with those ones subjected to anodising process were compared. Design/methodology/approach: The investigations were performed using light and electron microscopy for the microstructure determination. By mind of the transmission electron microscopy, especially selected area diffraction method appliance it was possible to determine the phases occurred in the alloy in the as cast state. The morphology and size of the layer was also possible to determine. Findings: Concerning the anodising conditions for surface hardening the influence was studied. The structure of the surface laser tray changes in a way, that there is a different thickness of the produced layer. Research limitations/implications: The aluminium samples were examined metallographically using optical microscope with different image techniques as well as light microscope. Practical implications: Improving the anodisation technology with appliance of different anodising conditions. Some other investigation should be performed in the future, but the knowledge found in this research concerning the proper process parameters for each type of alloy shows an interesting investigation direction. Originality/value: The combination of metallographic investigation for cast aluminium alloys - including electron microscope investigation - and anodising parameters makes the investigation very attractive for automobile, aviation industry, and others where aluminium alloys plays an important role.
