The influence of cast method and anodizing parameters on structure and layer thickness of aluminium alloys

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 metalographic examination, as well. Hardness of non-anodised alloys with those ones subjected to anodising process were compared.
