چکیده
L. Bernat, Poznan University of Technology, Faculty of Mechanical Engineering and Management, Division of Foundry, Poznan, Poland The paper presents an influence of the Dendrite Arm Spacing (DAS) microstructure parameter on the intergranular corrosion of AlSi7Mg aluminum alloy. The samples were subjected to the corrosion process for: 2,5; 12; 24; 48 and 96 hours in NaCl + HCl + H2O solution. It was noted that the DAS parameter significantly influenced on a distribution and depth of the intergranular corrosion of the hypoeutectic Al Si Mg silumin.
